Which is a correct statement of the second law of thermodynamics? Entropy of the universe is constantly increasing. Nature allows the conversion of potential energy into kinetic energy, but not vice versa. Heat is the only form of energy that can be converted into work with 100% efficiency. Energy cannot be created or destroyed, but it can change form.

Entropy of the universe is constantly increasing.

Explanation:

Entropy is the loss of available energy when it is in transit. The entropy of a system increases consuming the energy, this energy is now unavailable for doing the work or making the corresponding changes in the property of a system.

Entropy is the measure of randomness of a system. It is a toll that the nature takes for energy in transit.

The second law of thermodynamics concludes that all the energy cannot be transformed from one form to another and the flow of energy has a specific direction.

If a reversible process occurs, there is no net change in entropy. In an irreversible process, entropy always increases, so the change in entropy is positive. The total entropy of the universe is continuously increasing.
