Question

2. (10 pts) A typical pV cycle is shown in the figure. Indicate B Isotherm whether the indicated quantity (AU, Wor Q) increases Adiabat. decreases or stays the same (0) for the specified stage of the cycle by selecting the correct answer. Blank 2: A increases (+0, B) decreases or C) stays the same (0): W during Stage C Blank 3: A) increases (+0, B) decreases or C stays the same (0): W during Stage B Blank 4: A) increases (+0, B) decreases C) or CO stays the same (0): AU during Stage D Blank 5: A) increases B decreases Oor CO stays the same (0): Q during Stage C Blank 6: A) increases (+0, B) decreases or C) stays the same (0): Q during Stage A

Explanation / Answer

Blank 2 - As Volume is changed work is done, hence W decreases in the system (Also th eprocess is adiabatic)

Blank 3 - Here also the volume of the system increases hence W is decreased.

Blank 4 - Internal energy of the system will decrease as the volume decrease will decrese the temperature

5 = Will not change as the process is adiabatic
