Question

The incorrect option for cyclic process for an ideal gas is:

• A. $\Delta H=0$
• B. $W=0$
• C. $\Delta U=0$
• D. $\Delta S=0$

Answer 1

The correct option is B $W=0$

• $H,U,S$ are state functions. So, for cyclic process $\Delta H=\Delta U=\Delta S=0$
• W is a path junction, so for cyclic process work done $W$ is the area within the cyclic curve .
