That phenomenon, exacerbated by human industrialization, traps heat in the oceans and on land and raises the temperature of the entire globe.

The land produces an average of 0.8 kg of wheat or 5.5 kg of sugar beet. The dark soil raises the temperature of the ground which extends the annual growing period.

The power dissipated in a resistor is converted to heat. That heat raises the temperature of the device. The heat is conducted or radiated away. A simple linear characterization looks at the average power dissipated in the device (unit watts) and the device's thermal resistance (°C / Watt).

Stars form by gravitational collapse of interstellar gas clouds. As the collapse increases the density, radiative energy loss decreases due to increased opacity. This raises the temperature of the cloud which prevents further collapse, and a hydrostatic equilibrium is established. Gas continues to fall towards the core in a rotating disk.
|
|
In each of these fragments, the collapsing gas radiates away the energy gained by the release of gravitational potential energy. As the density increases, the fragments become opaque and are thus less efficient at radiating away their energy. This raises the temperature of the cloud and inhibits further fragmentation. The fragments now condense into rotating spheres of gas that serve as stellar embryos.

The Comprex system has two shortcomings; one, that the exhaust gases intermingles with the fresh air needed for combustion, leading to some recirculation of burnt gas. Secondly, this co-mingling also raises the temperature of the intake gas. Both of these are much less of a problem in a diesel than a petrol engine, hence the Comprex's rarity in petrol-engined applications.

Pythons are oviparous, that is, they lay eggs. This sets them apart from the family Boidae (boas), most of which bear live young (ovoviviparous). After they lay their eggs, females typically incubate them until they hatch. This is achieved by causing the muscles to "shiver", which raises the temperature of the body to a certain degree, and thus that of the eggs.

This energy, dispersed as molecular rotations, vibrations and/or translations in solids and liquids, raises the temperature of the food, in a process similar to heat transfer by contact with a hotter body. It is a common misconception that microwave ovens heat food by operating at a special resonance of water molecules in the food. As noted microwave ovens can operate at many frequencies.

A thin material may transmit a lot. A light-colored object may reflect much of the incident radiation and thus escape damage, like anti-flash white paint. The absorbed thermal radiation raises the temperature of the surface and results in scorching, charring, and burning of wood, paper, fabrics, etc. If the material is a poor thermal conductor, the heat is confined to the surface of the material.

The skins included in the fermentation of red wine provide some nutrients to the yeast. A byproduct of the energy created during fermentation is heat which raises the temperature of the fermenting must as the yeast work. When temperatures near 104°F (40°C), activity slows and yeast start to die. If temperatures stay high and the yeast stop reproducing then the fermentation is at grave risk of getting stuck.

In addition, the water released by the volcanoes could have been enough to cover all of Mars to a depth of 120 meters. The greenhouse effect of carbon dioxide raises the temperature of a planet by trapping heat in the form of infrared radiation. The volcanic eruptions on Tharsis could have made Mars more Earth-like in the past. Mars may have once had a much thicker and warmer atmosphere.

Waves or oscillations, lose energy over time, typically from friction or turbulence. In many cases, the "lost" energy raises the temperature of the system. For example, a wave that loses amplitude is said to dissipate. The precise nature of the effects depends on the nature of the wave: an atmospheric wave, for instance, may dissipate close to the surface due to friction with the land mass, and at higher levels due to radiative cooling.

High elevation cooking generally takes longer since boiling point is a function of atmospheric pressure. At an elevations of about , water boils at approximately 95 °C or 203 °F. Depending on the type of food and the elevation, the boiling water may not be hot enough to cook the food properly. Similarly, increasing the pressure as in a pressure cooker raises the temperature of the contents above the open air boiling point.

VAMTOX systems have a system of valves and dampers that direct the methane flow across the ceramic bed. On system start up, the system preheats and raises the temperature of the heat exchange material in the oxidizer bed to or above the auto-oxidation temperature of methane (1,000 °C or 1,832 °F). Then the preheating system is turned off and mine exhaust air is introduced. When the methane-filled air reaches the preheated bed, it oxidizes and releases heat.

Nick Nack leads Bond into Scaramanga's funhouse where Bond stands in the place of the mannequin of himself; when Scaramanga walks by, Bond outwits and kills him. Goodnight kills Scaramanga's security chief Kra, accidentally sending his body into one of the temperature control vats. His body heat raises the temperature of the helium cooling the solar plant, which begins to spiral out of control. Bond retrieves the Solex unit just before the island is destroyed, and they escape unharmed in Scaramanga's Chinese junk.

The first real effort to build a control fusion reactor used the pinch effect in a toroidal container. A large transformer wrapping the container was used to induce a current in the plasma inside. This current creates a magnetic field that squeezes the plasma into a thin ring, thus "pinching" it. The combination of Joule heating by the current and adiabatic heating as it pinches raises the temperature of the plasma to the required range in the tens of millions of degrees Kelvin.

Failure of Best Management Practices (BMPs) for forestry and agriculture, failure to control soil erosion from construction sites and bridge crossings, and increased stormwater runoff from developing urban and industrial areas have degraded the stream quality and pose a significant threat to the olive darters. Runoff and siltation caused by increasing habitat destruction raises the temperature of the water in many streams causing a change in the microclimate needed for the inhabitants of olive darters. This leads to loss of population.

Soil solarization is a simple method of weed control that is accomplished by covering the soil with a layer of clear or black plastic. The plastic that is covering the ground traps heat energy from the sun and raises the temperature of the soil. Many weed seeds and vegetative propagules are not able to withstand the temperatures and are killed. For this method to be most effective, it should be implemented during the summer months and the soil should be moist.

Clearcutting affects stream chemistry in the White Mountains of New Hampshire. Broomall, PA: US Department of Agriculture, Forest Service, Northeastern Forest Experiment Station. Clear-cutting also prevents trees from shading riverbanks, which raises the temperature of riverbanks and rivers, contributing to the extinction of some fish and amphibian species. Because the trees no longer hold down the soil, riverbanks increasingly erode as sediment into the water, creating excess nutrients which exacerbate the changes in the river and create problems miles away, in the sea.

Bessemer converter, schematic diagram The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. Related decarburizing with air processes had been used outside Europe for hundreds of years, but not on an industrial scale.

As the shock wave decays, the shocked region decompresses towards more usual pressures and densities. The damage produced by the shock wave raises the temperature of the material. In all but the smallest impacts this increase in temperature is sufficient to melt the impactor, and in larger impacts to vaporize most of it and to melt large volumes of the target. As well as being heated, the target near the impact is accelerated by the shock wave, and it continues moving away from the impact behind the decaying shock wave.

Typically, diamond is formed by heating carbon at very high temperatures (>5,000 K) and pressures (>120,000 atmospheres). However, Narayan and his group used kinetics and time control of pulsed nanosecond laser melting to overcome thermodynamic limitations and create a supercooled state that enables conversion of carbon into Q-carbon and diamond at ambient temperatures and pressures. The process uses a high-powered laser pulse, similar to that used in eye surgery, lasting approximately 200 nanoseconds. This raises the temperature of the carbon to approximately 4,000 K (3,700 °C; 6,700 °F) at atmospheric pressure.

NIF does this by heating the outer layer of a small plastic sphere with the world's most powerful laser. The energy from the laser is so intense that it causes the plastic to explode, squeezing down on the fuel inside. The speed of this process is enormous, with the fuel reaching a peak around 350 km/s, raising the density from about that of water to about 100 times that of lead. The delivery of energy and the adiabatic process during collapse raises the temperature of the fuel to hundreds of millions of degrees.

A quench is an abnormal termination of magnet operation that occurs when part of the superconducting coil enters the normal (resistive) state. This can occur because the field inside the magnet is too large, the rate of change of field is too large (causing eddy currents and resultant heating in the copper support matrix), or a combination of the two. More rarely a defect in the magnet can cause a quench. When this happens, that particular spot is subject to rapid Joule heating from the enormous current, which raises the temperature of the surrounding regions.

The oxidation also raises the temperature of the iron mass and keeps it molten. The "acid" Bessemer process had a serious limitation in that it required relatively scarce hematite ore which is low in phosphorus. Sidney Gilchrist Thomas developed a more sophisticated process to eliminate the phosphorus from iron. Collaborating with his cousin, Percy Gilchrist a chemist at the Blaenavon Ironworks, Wales, he patented his process in 1878;Thomas, Sidney Gilchrist at Welsh Biography Online Bolckow Vaughan & Co. in Yorkshire was the first company to use his patented process.

When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to measure the temperature of the environment, this electrical heating may introduce a significant error if a correction is not made. Alternatively, this effect itself can be exploited. It can, for example, make a sensitive air-flow device employed in a sailplane rate-of-climb instrument, the electronic variometer, or serve as a timer for a relay as was formerly done in telephone exchanges.

A Rankine cycle with a two-stage steam turbine and a single feedwater heater. In the case of a conventional steam-electric power plant using a drum boiler, the surface condenser removes the latent heat of vaporization from the steam as it changes states from vapor to liquid. The condensate pump then pumps the condensate water through a feedwater heater, which raises the temperature of the water by using extraction steam from various stages of the turbine. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.

Microwaves cannot be used in high dosage on edematous tissue, over wet dressings, or near metallic implants in the body because of the danger of local burns. Microwaves and short waves cannot be used on or near persons with implanted electronic cardiac pacemakers. Hyperthermia induced by microwave diathermy raises the temperature of deep tissues from 41 °C to 45 °C using electromagnetic power. The biological mechanism that regulates the relationship between the thermal dose and the healing process of soft tissues with low or high water content or with low or high blood perfusion is still under study.

The problems are the sediments that have built up and wash out filling in spawning beds should be controlled and directed, then eliminating any and all clear cutting of trees near river banks as it raises the temperature of the water, and stopping industrial discharges for obvious reasons. At 90 different dam sites it has been confirmed that after a dam is built the ecosystem does rebound. However, the trend will eventually slow, stop and in some cases decline. This is often due to anthropogenic chemical, light, and noise pollution as the large bodies of water draw human activity and recreation.

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output. Economizers lower stack temperatures which may cause condensation of acidic combustion gases and serious equipment corrosion damage if care is not taken in their design and material selection.

They supply higher current during the discharge process, resulting in a hotter and longer-duration spark. As the current of electrons surges across the gap, it raises the temperature of the spark channel to 60,000 K. The intense heat in the spark channel causes the ionized gas to expand very quickly, like a small explosion. This is the "click" heard when observing a spark, similar to lightning and thunder. The heat and pressure force the gases to react with each other, and at the end of the spark event there should be a small ball of fire in the spark gap as the gases burn on their own.

Colony of common bent-wing bats hanging in a cluster The common bent-wing bat is a bat that forms major colonies and the longest period of torpor (hibernation) observed was about 12 days. These colonies can range anywhere from a few dozen or several million bats. Most of these colonies are formed in large caves or mines but they can also be found in other areas such as tunnels or ruins or other man made sites. In these roosting sites the common bent-wing bat establishes its colony in a "bell- shaped" hollow, which traps body heat and raises the temperature of the roost higher than the surrounding portions of the cave.

In the absence of a countervailing process, the white dwarf would collapse to form a neutron star, in an accretion-induced non-ejective process, as normally occurs in the case of a white dwarf that is primarily composed of magnesium, neon, and oxygen. The current view among astronomers who model Type Ia supernova explosions, however, is that this limit is never actually attained and collapse is never initiated. Instead, the increase in pressure and density due to the increasing weight raises the temperature of the core, and as the white dwarf approaches about 99% of the limit, a period of convection ensues, lasting approximately 1,000 years. At some point in this simmering phase, a deflagration flame front is born, powered by carbon fusion.

Tuna and other fast-swimming ocean-going fish maintain their muscles at higher temperatures than their environment for efficient locomotion. Tuna achieve muscle temperatures or even higher above the surroundings by having a counterflow system in which the metabolic heat produced by the muscles and present in the venous blood, pre-warms the arterial blood before it reaches the muscles. Other adaptations of tuna for speed include a streamlined, spindle-shaped body, fins designed to reduce drag, and muscles with a raised myoglobin content, which gives these a reddish colour and makes for a more efficient use of oxygen. In polar regions and in the deep ocean, where the temperature is a few degrees above freezing point, some large fish, such as the swordfish, marlin and tuna, have a heating mechanism which raises the temperature of the brain and eye, allowing them significantly better vision than their cold-blooded prey.

When the beetle feels threatened it opens a valve which allows the aqueous solution from the reservoir to reach the vestibule. The catalases lining the vestibule wall facilitate the decomposition of hydrogen peroxide, as in the following theoretical reaction: :H2O2(aq) -> H2O(l) + 1/2O2(g) The peroxidase enzymes facilitate the oxidation of the hydroquinones into quinones (benzene-1,4-diol into 1,4-benzoquinone and analogously for methylhydroquinone), as in the following theoretical reaction: :C6H4(OH)2(aq) -> C6H4O2(aq) + H2(g) The known net reaction, which further accounts for the theoretical reaction of the H2(g) and 1/2O2(g) products of the previous reactions, is: :C6H4(OH)2(aq) + H2O2(aq) -> C6H4O2(aq) + 2H2O(l) Benzoquinone This reaction is very exothermic, and the released energy raises the temperature of the mixture to near 100 °C, vaporizing about a fifth of it. The resultant pressure buildup forces the entrance valves from the reactant storage chambers to close, thus protecting the beetle's internal organs. The boiling, foul-smelling liquid is expelled violently through an outlet valve, with a loud popping sound.
