A The energy change of a system undergoing any reversible process is zero
B It is not possible to transfer heat from a lower temperature to a higher temperature
C The total energy of system and surrounding remains the same
D None of the above

Correct Answer: None of the above

One of the corollaries of second law of thermodynamics states that heat can’t be continuously transferred from low temperature body to high temperature body without taking any external work. This is known as clausius statement of second law of thermodynamics.
