Heat

Overview
In physics and thermodynamics, heat is energy transferred from one body, region, or thermodynamic system to another due to thermal contact when the systems are at different temperatures. It is also often described as one of the fundamental processes of energy transfer between physical entities. In this description, it is an energy transfer to a body in any other way than due to work.[1]
