Air with a mass of 2 kg is heated at a constant pressure of 200 kPa to a temperature
of 500°C. Calculate the entropy change if the initial volume is 0.8 m3. Take ???? =
1.00 kJ/kg ? K and model air as an ideal gas. (Hint: Use the appropriate TdS [Gibbs] relation to calculate entropy change.)

Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720 kJ of work from a paddle wheel. Model the air as an ideal gas with constant specific heats. Evaluate the specific heats at 300 K. Neglect changes in kinetic energy and potential energy. Determine the mass of the air in kg,...

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...
