Carbon dioxide (CO2) is compressed in a piston–cylinder assembly from p1 = 0.7 bar, T1 = 280 K to p2 = 14 bar. The initial volume is 0.2 m3. The process is described by pV1.25 = constant. Assuming ideal gas behavior and neglecting kinetic and potential energy effects, determine the work and heat transfer for the process, each in kJ, using constant specific heats evaluated at 300 K, and data from Table A-23.

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...

A cylinder contains an ideal gas at the temperature of 300 K and is closed by a movable piston. The gas, which is initially at a pressure of 3 atm occupying a volume of 30 L, expands isothermally to a volume of 80 L. The gas is then compressed isobarically, returning to its initial volume of 30 L.

A cylinder contains 0.200 mol of carbon dioxide (CO2) gas at a temperature of 30.0 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The cylinder is placed on a hot plate and a 920 J of heat flows into the gas, thereby raising its temperature to 124 ∘C. Assume that the CO2 may be treated as an ideal gas.
