Noun
a form of energy that is transferred by a difference in temperature
Source: WordNetEfficiency The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. Source: Internet
Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Source: Internet
However, friction emerges when considering more complex structures of matter, whose surfaces can convert mechanical energy into heat energy when rubbed against each other. Source: Internet
However, she eventually displayed the ability to siphon heat energy and to detect electromagnetic signatures from broadcast transmissions. Source: Internet
In classical thermodynamics, the second law is a basic postulate applicable to any system involving heat energy transfer; in statistical thermodynamics, the second law is a consequence of the assumed randomness of molecular chaos. Source: Internet
In irreversible heat transfer, heat energy is irreversibly transferred from the higher temperature system to the lower temperature system, and the combined entropy of the systems increases. Source: Internet
