A rigid cylinder of volume 0.025 m^3 contains steam at 80 bar and 350o C. The cylinder is cooled until the pressure is 50 bar. Calculate the state of the steam after cooling and the amount of heat rejected by the steam. Sketch the process on the T-s diagram indicating the area which represents the heat flow. Also sketch the schematic of the system.

Steam at 275ºC and 15.0 bar is contained in a rigid tank with
the volume of 10.0 m3 . In a constantvolume cooling process, the
pressure inside the tank drops to 1.8 bar and some of the steam
condenses. Calculate 1) the temperature of the tank contents after
the process, 2) the amount of steam condensed during the process
(in kg), and 3) the amount of heat removed from the tank during the
process.

A piston–cylinder assembly contains propane, initially at 27°C,
1 bar, and a volume of 0.1 m3. The propane undergoes a process to a
final pressure of 4 bar, during which the pressure–volume
relationship is pV1.1 = constant. For the propane, evaluate the
work and heat transfer, each in kJ. Kinetic and potential energy
effects can be ignored.

3. An insulated container contains 2.7 kg of steam at 1.4 bar
and 120°C. The top is opened and a 1.8 kg block of ice at 0°C and
4.5 kg of liquid water at 1.6°C are dumped into the container. What
is the final temperature of the resulting vapor-liquid mixture in
the container? Note: It takes 6.0095 KJ/mol to melt ice.
