A piston - cylinder device, whose piston is resting on a set of stops, initially contains 2 kg of air at 300 kPa and 27 degree C. The mass of the piston is such that a pressure of 600 kPa is required to move it. Heat is now transferred to the air until its volume doubles.

a) Show the process on p - V and p - T diagrams.

b) Determine the work done by the air.

c) Determine the rate of heat transfer to the air.

1-kg water in a frictionless piston-cylinder device is initially at 250°C and 300 kPa (state 1). A total of 700 kJ of work is done ON the water in order to isothermally reduce its volume to 1/20 of its initial volume (state 2).

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...
