A.

The entropy of the system remains constant.

B.

The total energy of the system remains constant

C.

The total internal energy of the system remains constant.

D.

Work done by the system is equal to the heat transferred by the system.

Answer ( Option B)

The total energy of the system remains constant

Solution

The total amount of energy and matter in the universe remains constant, merely changing from one form to another. The first law of thermodynamics (conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.

Hence, the correct option is (B).
