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: -3.6 & 3.7 The Law of Conservation of Energy. According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another. KE + PE = constant.

Detailed explanation-3: -What is the Law of Conservation of Energy? 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-4: -1st Law of Thermodynamics-Energy cannot be created or destroyed. 2nd Law of Thermodynamics-For a spontaneous process, the entropy of the universe increases. 3rd Law of Thermodynamics-A perfect crystal at zero Kelvin has zero entropy.

Detailed explanation-5: -The Law of Conservation of Energy states that energy cannot be created nor destroyed, energy can only be transformed from one form into another, but the total amount of energy never changes.
