Aperfect gas is contained in a cylinder of fixed volume and is separated into two sections a and b by a frictionless piston; no heat can pass ugh the piston. section b is maintained at a constant temperature of 300k; that is, all changes in section b are isothermal. there are 2.00 mol of gas molecules in each section and the constant-volume heat capacity of the gas is 20]k mol", which can be assumed to be constant. initially t v, m - t, 300 k, v v 2.00 dm3. energy is then supplied as heat to section a so that the gas in a expands, pushing the piston out and thereby compressing
