Question

An ideal gas undergoes reversible expansion from the same initial state under two different conditions: isothermal and adiabatic. Which of the following statements correctly compares their P-V indicator diagrams?

Answer: D

💡 Solution & Explanation

The slope of the P-V curve for a reversible isothermal process is $-P/V$, whereas for an adiabatic process it is $-\gamma P/V$. Since the adiabatic index $\gamma > 1$, the adiabatic curve is mathematically steeper.
