A cylindrical chamber `A` of uniform cross section is divided into two parts `X` and `Y` by a movalbe piston `P` which can slide without friction inside the chamber. Initially part `X` contains `1 "mol"` of a monochromatic gas and `Y` contains `2 mol` of a diatomic gas, and the volumes of `X` and `Y` are in the ratio `1:2` with both parts `X` and `Y` being at the same temperature `T`. Assuming the gases to be ideal, the work `W` that will be done in moving the piston slowly to the position where the ratio of the volumes of `X` and `Y` is `2:1` will be
