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: -Energy cannot be created or destroyed, but it can change from more-useful forms into less-useful forms. As it turns out, in every real-world energy transfer or transformation, some amount of energy is converted to a form that’s unusable (unavailable to do work).
Detailed explanation-3: -Energy can neither be created nor destroyed, but can only be transformed or transferred from one form to another. For example, Solar cell panels do not create energy but harness solar energy and convert it into electrical energy. Further, electrical energy can be converted into light and heat energy in our homes.
Detailed explanation-4: -Yes, this is true according to law of conservation of energy, which says energy can neither be created nor be destroyed. It can only be transformed from one form to another.
