Law of energy conservation is a fundamental law of physics, as well as chemistry. According to the law of conservation of energy, energy can neither be created nor be destroyed. However, energy may be converted from one form to another. e.g sunlight converted to elctricity through solar cell.
When energy is converted to any other form, the measurement of the energy before and after conversion will remain unchanged.
