Question

For a reversible process, necessary condition is

• A. In the whole cycle of the system, the loss of any type of heat energy should be zero
• B. That the process should be too fast
• C. That the process should be slow so that the working substance should remain in thermal and mechanical equilibrium with the surroundings
• D. The loss of energy should be zero and it should be quasistatic

Answer 1

Answer: (D)

The loss of energy should be zero and it should be quasistatic

Answer 2
