To practice Problem-Solving Strategy 19.1 Work in Ideal-gas Processes.
A cylinder with initial volume V contains a sample of a gas at pressure p. On one end of the cylinder, a piston is let free to move so that the gas slowly expands in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, the piston is pushed in so that the gas is compressed isobarically to its original volume V. The gas is then cooled isochorically until it returns to the original volume and pressure.
Find the work W done on the gas during the entire process.

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

Water in a piston-cylinder assembly is initially at a pressure of 10 bar and a temperature of 500 C. The water is cooled and compressed at constant pressure until it becomes a saturated vapor. The water is then cooled at a constant volume until it reaches a temperature of 150 C. a) Sketch both processes on T-v and p-v diagrams (v here is specific volume). b) Determine the total work for the overall processes. c) Determine the heat transfer for...

A gas in a cylinder sealed with a piston having negligible friction has a pressure of 5 atm and a volume of 6 liters. The piston is pushed in order to compress the gas to 1/7 of its original volume. Assume that there is no change in the temperature of the gas. A valve is opened to let enough gas escape until the pressure is reduced back to its original original value of 5 atm. it is 14.3 % Then...
