The expression, nRT ln(P1/P2), is for the _____________of an ideal gas?
Correct answer: A. Work done under isothermal condition
- A. Work done under isothermal condition
- B. Work done under adiabatic condition
- C. Compressibility
- D. Co-efficient of thermal expansion
Explanation
For reversible isothermal expansion of an ideal gas, W = nRT ln(V2/V1). Since P1V1 = P2V2, this becomes W = nRT ln(P1/P2), identifying isothermal work.
