Question

Common Data: A thermodynamic cycle with an ideal gas as working fluid is shown below.



The above cycle is represented on $T-s$ plane by

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

We can observe in the $P-V$ diagram that temperature is not constant during any stage hence options $\left(b\right)$ and $\left(d\right)$ are rejected as temperature is constant during the state $3-1$ in both the options which is not possible option $\left(a\right)$ is rejected because clockwise process in $P-V$ diagram cannot have anticlockwise $T-S$ diagram. Hence the correct option is $\left(c\right)$
