Detailed explanation-1: -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-2: -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-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: -Instead, the law of conservation of energy says that energy is neither created nor destroyed. When people use energy, it doesn’t disappear. Energy changes from one form of energy into another form of energy.
