Question: A closed cylinder is divided into two rooms by a frictionless piston held in place by a pin. P5.85. Room A has 0.3 ft3 air

A closed cylinder is divided into two rooms by a frictionless piston held in place by a pin. P5.85. Room A has 0.3 ft3 air at 14.7 lbf/in 2, 90 F, and room B has 10 ft3 saturated water vapor at 90 F. The pin is pulled, releasing the piston and both rooms come to equilibrium at 90 F. Considering a control mass of the air and water, determine the work done by the system and the heat transfer to the cylinder.
