Question

For an isothermal expansion of a perfect gas, the value of \( \frac{\Delta P}{P} \) is equal to:

• A. \( -\gamma^{1/2} \frac{\Delta V}{V} \)
• B. \( -\gamma \frac{\Delta V}{V} \)
• C. \( \gamma \frac{\Delta V}{V} \)
• D. \( -\gamma^{1/2} \frac{\Delta V}{V} \)

Hint:

For an isothermal process, the change in pressure is inversely proportional to the change in volume.
