Question

What is thermal energy in EVS?

Answer 1

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.
