41Thermal resistance in electronics — Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt, or the equivalent… …
42Thermal degradation of polymers — is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.… …
43Thermal paper — is paper that is impregnated with a chemical that changes color when exposed to heat. It is used in thermal printers and particularly in cheap, lightweight devices such as adding machines, cash registers, and credit card terminals.The paper is… …
44Thermal radiation — is electromagnetic radiation emitted from the surface of an object which is due to the object s temperature. Infrared radiation from a common household radiator or electric heater is an example of thermal radiation, as is the light emitted by a… …
45Thermal physics — is the combined study of thermodynamics, statistical mechanics, and kinetic theory. This umbrella subject is typically designed for physics students and functions to provide a general introduction to each of three core heat related subjects.… …
46Thermal barrier coating — Thermal barrier coatings are highly advanced material systems applied to metallic surfaces, such as gas turbine or aero engine parts, operating at elevated temperatures. These coatings serve to insulate metallic components from large and… …
47Thermal laser stimulation — represents a class of defect imaging techniques which employ a laser to produce a thermal variation in a semiconductor device. [Harvnb|Beaudoin|Desplats|Perdue|Boit|2004] This technique may be used for semiconductor failure analysis. There are… …
48Thermal analysis — is a branch of materials science where the properties of materials are studied as they change with temperature. Techniques include: *Differential scanning calorimetry *Dynamic mechanical analysis *Thermomechanical analysis *Thermogravimetric… …
49Thermal energy — is the sum of the sensible energy and latent energy.Internal energy Internal energy – the sum of all microscopic forms of energy of a system. It is related to the molecular structure and the degree of molecular activity and may be viewed as the… …
50Thermal pollution — is a temperature change in natural bodies of water caused by human influence. The temperature change can be upwards or downwards. In the Northern Hemisphere, a common cause of thermal pollution is the use of water as a coolant, especially in… …
