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: -The law of conservation of energy states that energy can neither be created nor destroyed-only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside.
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.
