A two-phase system contains both liquid and gaseouswater, so its equilibrium pressure is determined by the temperature. Calculate the cyclic integral of dw_rev for the following process: The volume of the system is changed from 10.00 l to 20.00 l at a constant temperature of 25.00^◦ C, at which the pressure is 24.756 torr. The system is then heated to a temperature of 100.0^◦ C at a constant volume of 20.00 l. The system is then compressed to a volume of 10.00 l at a temperature of 100.0^◦ C, at which the pressure is 760.0 torr. The system is then cooled from 100.0^◦ C to a temperature of 25.00^◦ C at a constant volume of 10.00 l. Remember to use consistent units.
