Detailed explanation-1: -In physics, the law of conservation of energy states that the total energy of an isolated system remains constant-it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms 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: -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.

Detailed explanation-4: -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-5: -Not always. Nuclear fission and Nuclear fusion are the reactions which contradicts it. Because there mass-energy transition occurs which means some energy will be converted to mass and vice-versa. So, this contradicts.
