Maximum work that could be secured by expanding the gas over a given pressure range is the _____________ work?
Correct answer: A. Isothermal
- A. Isothermal
- B. Adiabatic
- C. Isentropic
- D. None of these
Explanation
For expansion between fixed pressure limits, an isothermal path maintains the gas at the highest temperature relative to an adiabatic path and therefore gives the greatest work for an ideal gas. Adiabatic and isentropic expansion produce less work over the same limits.
