A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 3.00 L and the pressure is initially 105 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 65.0 J of work is then done on the piston, compressing the gas (in other words, the gas does −65.0 J of work). The work is done very slowly so that the gas maintains a...

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...
