Question:
A piston–cylinder assembly contains a fixed mass of air. The air is the system of interest and undergoes a finite process from state 1 to state 2. The piston moves such that the final (state-2) volume of the air is several times smaller than the initial volume (state 1). The process occurs at constant temperature.
A. Does the pressure increase or decrease? Explain your answer.
B. Is there any work associated with the process? If so, is the work done on or by the system? Explain your answer.
C. Does the internal energy of the system increase, decrease, or remain the same? Explain your answer.
D. Is there any heat interaction associated with the process? If so, is the heat interaction into or out of the system? Explain your answer.
