MHT CET 2025 Physics question

In a cyclic process, work done by the system is

(A)more than the heat given to the system.
(B)equal to the heat given to the system.Correct
(C)zero.
(D)independent of the heat given to the system.

Answer: (B)

Solution

In a cyclic process the system returns to its initial state, so the change in internal energy (a state function) is zero: . By the first law, . Hence the net work done by the system equals the net heat given
