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 \(\gamma\)for the gas is best given by
- \(1-2^{-7}=(\gamma-1) \ln 2\)
- \(1-2^{-(-1)}=(\gamma-1) \ln 2\)
- \(1-2^{-(\gamma-1)}=2(\gamma-1) \ln 2\)
- None of these
Answer
(B) 1-2^ -(-1) =( -1) 2
