An ideal monatomic gas expands quasi-statically to twice its volume. If the process is isothermal, the work done by the gas is W i . If the process is adiabatic, the work done by the gas is W a .

Question

An ideal monatomic gas expands quasi-statically to twice its volume. If the process is isothermal, the work done by the gas is $W_{i}$ . If the process is adiabatic, the work done by the gas is $W_{a}$ . Which of the following is true?

Options:

Answer:

D

Solution:

Both are positive; the isothermal curve lies above the adiabatic for $V > V_{i}$ , so $W_{i} > W_{a} > 0$ .
