Question

What is heat energy? please answer​

Answer 1

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}, in a system that is described in terms of its microscopic particulate constituents, where {\displaystyle T} denotes temperature and {\displaystyle k_{\mathrm {B} }} denotes the Boltzmann constant.
