A cylinder fitted with a piston and a set of stops is filled with air (Figure 7.8). The piston cross-section is 0.8 ft? and the air inside is initially at 20 psig and 800 °F. The air is then cooled at constant pressure as a result of heat transfer to the surroundings. a. what is the temperature of the air inside the cylinder when the piston reaches the stops? How much work is done during the cooling process? How much heat is rejected? b. The cooling continues after the piston reaches the stops until the temperature reaches 70 °F.. What is the pressure at this state? How much work is done during this process? How much heat is rejected?

Please help to solve complete solution.

Thermodynamics

One mole of an ideal gas is heated slowly so that it goes from the PV state (P, V;) to (2P;, 2V;) in such a way that the pressure is directly proportional to the volume. (a) How much work is done on the gas in the process? (Use any variable or symbol stated above along with the following as necessary: n and R.) W = (b) How is the temperature of the gas related to its volume during this process? (Do not substitute numerical values; use variables only. Use the following as necessary: n, R, V, Vi, and P.)
