MHT CET 2026 Physics question

In a cyclic process, work done by the system is

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

Answer: (B)

Solution

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