Question

Why second law of thermodynamics is known as law of degradation of energy

Answer 1

The Second law of thermodynamics have many statements. It is also called as the Law of the degradation of the Energy.

It states that no Heat Engine in this whole Universe can have the efficiency equal to 100%, under Ideal Conditions. (when there will be no friction or any dissipating force).

This law states if energy is transferred to the system then whole energy cannot be converted to the work, some will move in the sink, which must be there for the flow of the heat.

Hence, there must be the loss of the energy to the sink without which the system cannot work. Thus, the energy is said to be degraded and Second law of the Thermodynamics also called as the Degradation of the energy.
