For a reversible process, necessary condition is

Physics Thermodynamics Heat, Carnot Engine, Refrigerator and Second Law of Thermodynamics MCQ (Single Correct)

In the whole cycle of the system, the loss of any type of heat energy should be zero

That the process should be too fast

That the process should be slow so that the working substance should remain in thermal and mechanical equilibrium with the surroundings

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

Text Solution

Verified by Experts

The correct answer is:

Quasistatic takes care of the thermal, mechanical and chemical equilibrium (thermodynamic

equilibria). No dissipative forces like friction, viscosity or electrical resistance etc. must be there which create a loss of energy.
