Question

For cyclic process, the condition is:

• A. $\Delta U=0$
• B. $\Delta H=0$
• C. $\Delta U>0$ and $\Delta H>0$
• D. both $\Delta U=0$ and $\Delta H=0$

Answer 1

The correct option is D both $\Delta U=0$ and $\Delta H=0$

Hence For any cyclic process, the initial and final stages are same. Hence, there is no change in temperature. So, the value of both $\Delta H=0$ and $\Delta U=0$.

Hence, the answer is option $D$.
