Two samples A and B of same gas have equal volumes and pressures. The gas in sample A is expanded isothermally to double its volume and the gas in sample B is expanded to double its volume adiabatically. If work done by the gas is same in two processes, then value of γ for the gas is best given by
- 1 – 2– = (– 1) ln 2
- 1 – 2–( – 1) = ( – 1) ln 2
- 1 – 2–( – 1) = 2 ( – 1) ln 2
- None of these
Answer
(B) 1 – 2–( – 1) = ( – 1) ln 2
