Detailed explanation-1: -First law of thermodynamics states that total energy of an isolated system is constant, energy can neither be created nor be destroyed but can be transformed from one form to another.

Detailed explanation-2: -In mechanics, there are three fundamental quantities which are conserved. These are energy, momentum and angular momentum. If you have looked at examples in other articles-for example, the kinetic energy of charging elephants-then it may surprise you that energy is a conserved quantity.

Detailed explanation-3: -The first law of thermodynamics thinks big: it deals with the total amount of energy in the universe, and in particular, it states that this total amount does not change. Put another way, the First Law of Thermodynamics states that energy cannot be created or destroyed.

Detailed explanation-4: -The law of conservation of energy states that energy can neither be created nor be destroyed. Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant.

Detailed explanation-5: -According to the law of conservation of energy, energy cannot be created or destroyed. It can, however, be transformed from one form to another. When all forms of energy are considered, the total energy of an isolated system remains constant.
