Problem
A piston can move freely inside a horizontal cylinder closed at both ends. Initially, it separates the cylinder into two equal parts, each of volume V0, containing an ideal gas at the same pressure P0 and temperature. What work must be performed to make the volume of one gas part isothermally η times that of the other by slowly moving the piston?
