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

The correct Answer is:
A, B, C
Fig `A: W_(A) = +ve` `" "` Fig `B: W_(B) = +ve`
Fig `C : W_(C) = +ve` `" "` Fig `D : W_(D) = -ve`
`therefore` In process Fig - `(D`) , heat is released.
