Detailed explanation-1: -The first law of thermodynamics is based on the law of conservation of energy, which states that energy cannot be created or destroyed, but can be transferred from one form to another.

Detailed explanation-2: -1st Law of Thermodynamics-Energy cannot be created or destroyed. 2nd Law of Thermodynamics-For a spontaneous process, the entropy of the universe increases.

Detailed explanation-3: -The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase. The final entropy must be greater than the initial entropy for an irreversible process: Sf > Si (irreversible process)

Detailed explanation-4: -First laws of thermodynamics states that total energy of an isolated system is constant and energy can neither be created nor be destroyed but can be transformed from one form to another.

Detailed explanation-5: -The First Law of Thermodynamics states that the net heat energy supplied to the system is equal to sum of change in internal energy of the system and work done by the system. This means that heat energy cannot be created or destroyed.
