The laws of thermodynamics dictate energy behavior, for example, how and why heat, which is a form of energy, transfers between different objects. The first law of thermodynamics is the law of conservation of energy and matter. In essence, energy can neither be created nor destroyed; it can, however, be transformed from one form to another.

A black body is a body or surface which is not reflective at all. In other words, a black body is a body with absorptivity of 1 and hence it absorbs the entire radiation without reflecting any (Howard, 2000). On the other hand, a grey body refers to a body that reflects some of the radiation and hence its absorptivity is less than 1.
