What is a cyclic process?
Advertisements
उत्तर
This is a thermodynamic process in which the thermodynamic system returns to its initial state after undergoing a series of changes. Since the system comes back to the initial state, the change in the internal energy is zero. In the cyclic process, heat can flow into the system and heat flows out of the system. From the first law of thermodynamics, the net heat transferred to the system is equal to the work done by the gas.
