A piston–cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 50%. The ammonia is slowly heated to a final state where the pressure is 6 bar and the temperature is 100°C. While the ammonia is heated, its pressure varies linearly with specific volume.

For the ammonia, determine the work and heat transfer, each in kJ/kg.

Water, initially (state 1) a saturated liquid at 1100C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. If the change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature, determine (a) heat transfer using first law of thermodynamics in kJ/kg and (b) heat transfer using second law of thermodynamics...

A 0.2 m3 piston-cylinder initially contains 400 K air. A heavy frictionless piston maintains a pressure of 500 kPa abs. Then, a weakness in the cylinder wall blows out and creates a hole. Air escapes through the hole until the piston drops far enough to cover the hole. At that point, the volume is half the initial volume. During this process, 75 kJ of heat is transferred to the 100 kPa, 300 K surroundings. Using Cp = 1.005 kJ/kg-K and...
