Questions 13-14
A certain quantity of an ideal gas initially at temperature `T0`, pressure `p0`, and volume `V0` is compressed to one-half its initial volume. As shown above, the process may be adiabatic (process 1), isothermal (process 2), or isobaric (process 3).
13. Which of the following is true of the mechanical work done on the gas?
(A) It is greatest for process 1 .
(B) It is greatest for process 2.
(C) It is greatest for process 3.
(D) It is the same for all three processes.
