A 220-ft3 sample of gas at standard temperature and pressure is compressed into a cylinder, where it exerts pressure of 2000 psi. Calculate the work (in J) performed when this gas expands isothermally against an opposing pressure of 1.0 atm. (The amount of work that can be done is equivalent to the destructive force of about 1/4 lb of dynamite, giving you an idea of how potentially destructive compressed gas cylinders can be if improperly handled!)

Answer the following questions with complete/step-by-step solutions: (Note: The following problems are interconnected to each other.) Problem 1. A quantity of an ideal gas in an isolated system is expanded isothermally and reversibly at 400 degrees Kelvin from a volume V1 to V2. During the expansion the gas absorbs 200 calories of heat from the reservoir in contact with it. Find (a) the entropy change of the gas, (b) the entropy change of the reservoir and (c) the entropy change of the whole system. Problem 2. If the gas in problem 1 is expanded from V1 to V2 isothermally but irreversibly at 400 degrees Kelvin with an absorption of 100 calories of heat, what will be the entropy changes for (a) the gas, (b) the reservoir, (c) the complete system? Problem 3. Suppose the gas in problem 1 expands freely from V1 to V2 at 400 degrees Kelvin. What will be the entropy changes for (a) the gas, (b) the reservoir, and (c) the entire system?
