Question

The idealized P-V diagram above shows a complete cycle through compression and expansion of a gas. The questions below relate to the processes within the cycle.
Which letter shows an adiabatic expansion?

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

The correct option is A A

The volume of the gas is increasing during part A in the diagram. Thus, A part will represent the adiabatic expansion.
