Question

A monatomic ideal gas undergoes an adiabatic expansion to double its volume. the same final state can be reached by an isobaric expansion followed by an isochoric cooling. what is the ratio of work done by the system between the first and the second processes?

Answer 1

(2^(1-γ)-1)/(1-γ) where γ is the heat capacity ratio, Cp/Cv. See attached image for the working.
