The following are the `P-V` diagrams for cyclic processes for a gas. In which of these processes is heat absorbed by the gas?

A

B

C

D

Text Solution

Verified by Experts

In a cyclic process, heat is absorbed by a gas when the work done by it is positive, i.e. when work is done by the gas
Hence a, b, c, are correct.
