Question

A gas in a piston-cylinder system is expanded to double its volume, once by an isobaric process and once by an isothermal process from the same initial state. In which process does the gas do more work?

TestHub · Accepted Answer

Isobaric: W = P Δ V = P V 0 ​ = n R T 0 ​ . Isothermal: W = n R T 0 ​ ln 2 = 0.69 n R T 0 ​ . The isobaric work is larger. A.
