define thermal energy?
Answers
Answer:
The term 'thermal energy' is used differently, and often loosely, in different contexts. It refers to several distinct physical concepts, such as the internal energy, or as the enthalpy, of a body of matter and radiation; or as heat, defined as a type of energy transfer (as is thermodynamic work); or as the characteristic energy of a degree of freedom, {\displaystyle k_{\mathrm {B} }T} {\displaystyle k_{\mathrm {B} }T}, in a system that is described in terms of its microscopic particulate constituents, where {\displaystyle T} T denotes temperature and {\displaystyle k_{\mathrm {B} }} k_{\mathrm{B}} denotes the Boltzmann constant.
Answer
The kinetic energy associated with the random motions of the molecules of a material or object; often used interchangeably with the terms heat and heat energy
