This includes wood and wood byproducts, municipal waste, methane from landfills, and fuel from agricultural crops. KT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on E / kT.

More simply put, heat energy, also called thermal energy or simply heat, is transferred from one location to another by particles bouncing into each other.

The faster the atoms are moving, the higher the temperature. (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact. Most of us refer the word ‘heat’ to anything that feels warm but scientifically, heat is defined as the flow of energy from a warm to a cooler object.
