Thermal radiation is an important mechanism of heat transfer.

Thermal radiation is a common synonym for approximately black body radiation spontaneously emitted from objects, that is chiefly infrared electromagnetic radiation at temperatures often encountered on Earth.

Thermal radiation is generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation.

* Thermal infrared spectroscopy measures thermal radiation emitted from materials and surfaces and is used to determine the type of bonds present in a sample as well as their lattice environment.

** Thermal radiation

Thermal radiation moves from a warmer surface to a cooler one.

Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body.

* Thermal radiation

* Thermal Doppler broadening: The atoms in a gas which are emitting radiation will have a distribution of velocities.

Thermal radiation is energy emitted by matter as electromagnetic waves due to the pool of thermal energy that all matter possesses that has a temperature above absolute zero.

Thermal radiation propagates without the presence of matter through the vacuum of space.

Thermal radiation is a direct result of the random movements of atoms and molecules in matter.

Thermal radiation in visible light can be seen on this hot metalwork.

Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter.

Thermal radiation is different from thermal convection and thermal conduction -- a person near a raging bonfire feels radiant heating from the fire, even if the surrounding air is very cold.

Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero.

* Thermal radiation emitted by a body at any temperature consists of a wide range of frequencies.

Thermal X-ray radiation from hot gas and non-thermal emission from relativistic electrons can be seen in the blue ' shells ' around the lobes, particularly to the south ( bottom ).

Thermal energy storage refers to technologies that store energy in a thermal reservoir for later use.

Simultaneous Thermal Analysis ( STA ) generally refers to the simultaneous application of Thermogravimetry ( TGA ) and differential scanning calorimetry ( DSC ) to one and the same sample in a single instrument.

Rapid Thermal Processing ( or RTP ) refers to a semiconductor manufacturing process which heats silicon wafers to high temperatures ( up to 1, 200 ° C or greater ) on a timescale of several seconds or less.

Thermal runaway refers to a situation where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result.

The integrated Dynamic Cable Rating ( DCR ) or also called Real Time Thermal Rating ( RTTR ) solution enables not only to continuously monitor the temperature of a high voltage cable circuit in real time, but to safely utilize the existing network capacity to its maximum.

Thus the reaction will only be allowed if the total entropy change of the universe is equal to zero ( a Thermal equilibrium state ) or positive.

Thermal equilibrium does not mean the same as thermodynamic equilibrium, because the latter requires that there be equilibrium of all kinds, not only thermal, and that there be no flow of any kind, in the system of interest.

The orbiter sustained only minor Thermal Protection System tile damage, and the redesigned post-Challenger solid rocket boosters showed no signs of leakage or overheating at any of the joints.

Thermal and mineral springs are both found close to the centre of the town, as is the world's only hot soda water geyser.

However, this was not XIII Sqn's only contribution to the coalition victory, for the Sqn was also fundamental to the success of the Tornado / TIALD ( Thermal Imaging And Laser Designation ) combination.

Most psychrometric charts used in HVAC design only show the dry bulb temperature on the x-axis ( abscissa ), however, it is the operative temperature which is specified on the x-axis of the psychrometric chart illustrated in ANSI / ASHRAE Standard 55 – Thermal Environmental Conditions for Human occupancy.

The only possible exception is moissanite, which has a thermal conductivity similar to diamond: older probes can be fooled by moissanite, but newer Thermal and Electrical Conductivity testers are sophisticated enough to differentiate the two materials.

The Thermal Contraction Theory states that during the winter months, thermal contraction cracks form only a few cm wide and a couple of metres deep because of the extreme cold weather.

Bakreshwar Thermal Power Station is the only heavy industry in the district.

Bakreshwar Thermal Power Station ( 210 MW x 3 + 210 MW x 2 under construction ) is the only heavy industry in the district.

By 2005, not only had a working thermal-powered glider ( Slocum Thermal ) been demonstrated by Webb Research ( founded by Doug Webb ), but they and other institutions had introduced battery-powered gliders with impressive duration and efficiency, far exceeding that of traditional survey-class AUVs.

The Baños de Coamo (; the " Baths of Coamo " or " Coamo Thermal Baths "), located in the municipality of Coamo, are Puerto Rico's only thermal springs.

Thermal energy manifests itself as energy of motion.

Thermal expansion of the fuel itself can also provide quick negative feedback.

Thermal depolymerization also destroys prions in infected organic and inorganic matter, since the process chemically attacks protein at the molecular level.

Thermal erosion also affects the Arctic coast, where wave action and near-shore temperatures combine to undercut permafrost bluffs along the shoreline and cause them to fail.

Thermal mass may also be used for bodies of water, machines or machine parts, living things, or any other structure or body in engineering or biology.

A much higher quality DEM from the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) instrument of the Terra satellite is also freely available for 99 % of the globe, and represents elevation at a 30 meter resolution.

Thermal expansion associated with temperature increase also contributes a negative coefficient of reactivity since fuel atoms are moving farther apart.

Thermal noise is intrinsic to all resistors and is not a sign of poor design or manufacture, although resistors may also have excess noise.

Thermal conductivity is measured in watts-per-meter per kelvin ( W · m < sup >− 1 </ sup >· K < sup >− 1 </ sup >), represented as k. As the thickness of insulating material increases, the thermal resistance — or R-value — also increases.

Thermal mass flow meter ( also called thermal dispersion flowmeter ) technology is used for compressed air, nitrogen, helium, argon, oxygen, and natural gas.

See also: tog ( unit ) or Thermal Overall Grade ( where 1 tog = 0. 1 m² K / W ), used for duvet rating.

Thermal analysis is also often used as a term for the study of heat transfer through structures.

The Hospital Termal Rainha D. Leonor ( Queen Leonor Thermal Hospital ), a spa offering medically prescribed treatment in sulfurous waters, is also part of the Centro Hospitalar.

Thermal pollution can also be caused by the release of very cold water from the base of reservoirs into warmer rivers.

Thermal oxidation ( or incineration ) can also be an effective remediation technology.

It is called Harduaganj Thermal Power Station ( also referred as Kasimpur Power House ).

Thermal grease ( also called thermal gel, thermal compound, thermal paste, heat paste, heat sink paste or heat sink compound ) is a viscous fluid substance, originally with properties akin to grease, which increases the thermal conductivity of a thermal interface by filling microscopic air-gaps present due to the imperfectly flat and smooth surfaces of the components ; the compound has far greater thermal conductivity than air ( but far less than metal ).

Thermal lows also occur over continental areas across the subtropics during the summer such as the Sonoran Desert, the Mexican plateau, Sahara, South America, and Southeast Asia.

The Thermal Energy Storage ( TES-2 ) experiment also is part of the CAPL-2 / GBA-6.

* Thermal mineral water springs () in the vicinity of Peshkopi are a draw for seasonal tourism, primarily from within Albania, but also to a lesser extent from neighboring countries.

Chubu Electric Power also has a large electrical generating facility, the Taketoyo Thermal Power Plant located in Taketoyo.

* in-situ thermal desorption ( see also Thermal blanket )

Thermal keratoplasty can also be used to improve presbyopia or reading vision after age 40.
