Heated glass is a resistance heater created when a transparent, electrically conductive coating is applied to float glass and then subjected to an electric current. The electric current in the coating creates heat energy, which warms the glass until the glass radiates heat.

In that state, the reactor vessel radiates heat, but the vessel and fuel spheres remain intact and undamaged. The machinery can be repaired or the fuel can be removed. These safety features were tested (and filmed) with the German AVR reactor. All the control rods were removed, and the coolant flow was halted.

He wears a duffel coat unbuttoned and with the hood up, a pale shirt and trousers, and some old scruffy boots. He glows with an eerie luminosity that in spite of his snowy appearance radiates heat. It seems somewhat animal-like, both rousing and repelling her. His beauty comes not from himself or from the primal energy he exudes.

In radiation, the heated atoms make electromagnetic emissions absorbed by remote other atoms, whether nearby or at astronomical distance. For example, the Sun radiates heat as both invisible and visible electromagnetic energy. What we know as "light" is but a narrow region of the electromagnetic spectrum. If, in a place or thing, more energy is received than is lost, its temperature increases.

Convection cells in a gravity field A convection cell, also known as a Bénard cell is a characteristic fluid flow pattern in many convection systems. A rising body of fluid typically loses heat because it encounters a colder surface. In liquid, this occurs because it exchanges heat with colder liquid through direct exchange. In the example of the Earth's atmosphere, this occurs because it radiates heat.

The thermal mass which encloses the exhaust duct and absorbs heat from the hot combustion gases is the interface that radiates heat to the environment. It can be made of cob, rocks, or pebbles. The thermal mass is often sculpted into a bench which can become an architectural feature of the home, radiating thermal energy into the space for several days after the wood fuel is exhausted.

Sear-grill and gear grilling is a process of searing meat or food items with an infrared grill. In sear grilling, propane or natural gas is used to heat a ceramic plate, which then radiates heat at temperatures over 480 °C (900 °F). Sear-grilling instantly sears the outside of meat to make the food more flavorful. Commonly, grilling heats the surrounding air to cook food.

A city with miles of dark hot pavement absorbs and radiates heat into the surrounding atmosphere at a greater rate than a natural landscapes do. This is urban heat island effect causing an increase in air temperatures. The EPA estimates that the average air temperature of a city with one million people or more can be 1.8 degrees to 5.4 degrees F warmer than surrounding areas. Higher temperatures reduce air quality by increasing smog.

Interior of an air fryer Air fryers use a circulation of hot air to cook food that would otherwise be submerged in oil. The air fryer's cooking chamber radiates heat from a heating element near the food, and a fan circulates hot air. There is an air inlet on the top and an exhaust at the back that controls the temperature by releasing any excess hot air. The temperatures can go up to 230 °C (445 °F) depending on the model.

Atkinson added, however, that "South American contributes the [revue's] most magnetic personality" (Miranda). Singing "rapid-rhythmed songs to the accompaniment of a Brazilian band, she radiates heat that will tax the Broadhurst [theater] air-conditioning plant this Summer". Although Atkinson gave the revue a lukewarm review, he wrote that Miranda made the show. Syndicated columnist Walter Winchell wrote for the Daily Mirror that a star had been born who would save Broadway from the slump in ticket sales caused by the 1939 New York World's Fair.

The rate at which energy reaches Earth as sunlight, and leaves Earth as heat radiation to space, must balance, or the total amount of heat energy on the planet at any one time will rise or fall, resulting in a planet that is warmer or cooler overall. An imbalance between the rates of incoming and outgoing radiation energy is called radiative forcing. A warmer planet radiates heat to space faster, so eventually a new balance is reached, with a higher planetary temperature. However, the warming of the planet also has knock-on effects.

An electric underfloor heating system has heating cables embedded in the floor. Current flows through a conductive heating material, supplied either directly from the line voltage (120 or 240 volts) or at low voltage from a transformer. The heated cables warm the flooring by direct conduction and will switch off once it reaches the temperature set by the floor thermostat. A warmer floor surface radiates heat to colder surrounding surfaces (ceiling, walls, furniture.) which absorb heat and reflects all non absorbed heat to yet other still cooler surfaces.

To combat temperature variations of over 200 degrees Fahrenheit without relying on physical shutters or heat pipes that consume large amounts of power, the phase change behaviour of vanadium dioxide is used instead. At low temperatures it acts as an insulator, and at high temperatures it is a conductor which radiates heat. With a 20 fold improvement in temperature management, this research may have applications in maintaining building temperatures. In 2019 it was announced that the research group of Povinelli will work in the Breakthrough Starshot project, towards a proof-of-concept demonstration of ultra-fast light-driven nanocrafts.

In a direct-gain passive solar system, the indoor space acts as a solar collector, heat absorber, and distribution system. South-facing glass in the northern hemisphere(north- facing in the southern hemisphere) admits solar energy into the building interior where it directly heats (radiant energy absorption) or indirectly heats (through convection) thermal mass in the building such as concrete or masonry floors and walls. The floors and walls acting as thermal mass are incorporated as functional parts of the building and temper the intensity of heating during the day. At night, the heated thermal mass radiates heat into the indoor space.

The surface of the Sun radiates light and heat at approximately 5,500 °C. The Earth is much cooler and so radiates heat back away from itself at much longer wavelengths, mostly in the infrared range. The idealized greenhouse model is based on the fact that certain gases in the Earth's atmosphere, including carbon dioxide and water vapour, are transparent to the high-frequency, high- energy solar radiation, but are much more opaque to the lower frequency infrared radiation leaving the surface of the earth. Thus heat is easily let in, but is partially trapped by these gases as it tries to leave.

In 1791, Pierre Prévost showed that all bodies radiate heat, no matter how hot or cold they are. In 1804, Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black-body radiation. Though it had become to be suspected even from Scheele's work, in 1831 Macedonio Melloni demonstrated that black-body radiation could be reflected, refracted and polarised in the same way as light. James Clerk Maxwell's 1862 insight that both light and radiant heat were forms of electromagnetic wave led to the start of the quantitative analysis of thermal radiation.

At the same time, the removal of the exhaust gasses through the inner flue allows for relatively cold air to be drawn into the firebox through the outer flue. As the firebox heats up due to the operation of the burners, it radiates heat into the room through the porous glass face that separates the firebox from the inside of the room. At the same time, it transfers heat through the surrounding metal walls into the empty space in between itself and the outer housing. This heat transfer creates a convection process inside of the empty space that is very similar to the one that takes place inside of the firebox.

The heat conductivity of metal is much better than that of air, and it radiates heat better than the component that it is protecting (usually an integrated circuit or CPU). Fan- cooled aluminium heatsinks were originally the norm for desktop computers, but nowadays many heatsinks feature copper base-plates or are entirely made of copper. Dust buildup between the metal fins of a heatsink gradually reduces efficiency, but can be countered with a gas duster by blowing away the dust along with any other unwanted excess material. Passive heatsinks are commonly found on older CPUs, parts that do not get very hot (such as the chipset), and low-power computers.

The Chyornaya Rechka ( "Black River"), originally Mustajogi (in the Karelian language), is a small river in Saint Petersburg. It is 8.1 kilometres long, and flows into the Great Nevka, a branch of the Neva. The Chyornaya Rechka is known for famous duels that took place there, including the 1909 duel between Nikolai Gumilyov and Maximilian Voloshin over the matter of a fictitious poet called Cherubina de Gabriak [in the Finnish language: Kaprijakin (Kaprion) Kerubitar], and the fatal duel between poet-playwright Alexander Pushkin and Georges d'Anthès. The Chyornaya Rechka contributes to St. Petersburg's weather - since water absorbs and radiates heat slower than land it makes temperatures less extreme in a place so close to the polar zone.

The 1880 edition of A Guide to the Scientific Knowledge of Things Familiar, a 19th-century educational science book, explained heat transfer in terms of the flow of caloric. In 1804, Sir John Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black-body radiation. In 1808, John Dalton defended caloric theory in A New System of Chemistry and described how it combines with matter, especially gases; he proposed that the heat capacity of gases varies inversely with atomic weight. In 1824, Sadi Carnot analyzed the efficiency of steam engines using caloric theory; he developed the notion of a reversible process and, in postulating that no such thing exists in nature, laid the foundation for the second law of thermodynamics.
