1.	A sample of an ideal gas with initial pressure 'P' and volume 'V' is taken through an isothermal process during which entropy change is found to be DS. The work done by the gas is
Answer» `(PV Delta S)/(NR)` `n R Delta S` PV `(P Delta S)/(NRV)` Solution :`Delta S = nR l n (V_(2))/(V_(1)), W = nRT l n (V_(2))/(V_(1))` `rArr W = T. Delta S = Delta S xx (PV)/(nR)`
