Thermodynamics 1st law:
This law is often called the law of conservation of energy. Simply stated , this law states that energy can be changed from one to another but it cannot be created or destroyed. Energy constantly changes from one to another, but the total amount of energy available in the universe is constant.……….
The 2nd law of Thermodynamics: This law states that in all energy stages, if no energy enters or leaves the system, the potential energy of the new state will always be less than that's of the new initial state.
