Question:medium
An ideal gas of mass \( M \) in the state \( A \) goes to another state \( B \) via three different processes. If \( Q_1, Q_2 \) and \( Q_3 \) denote the heat absorbed by the gas along the paths 1, 2 and 3 respectively, then
An ideal gas of mass \( M \) in the state \( A \) goes to another state \( B \) via three different processes. If \( Q_1, Q_2 \) and \( Q_3 \) denote the heat absorbed by the gas along the paths 1, 2 and 3 respectively, then
Show Hint
- Same initial & final states $\Rightarrow \Delta U$ same
- Compare areas under P–V curve to compare heat
Updated On: May 4, 2026
- \( Q_1 < Q_2 < Q_3 \)
- \( Q_1 < Q_2 = Q_3 \)
- \( Q_1 = Q_2 > Q_3 \)
- \( Q_1 > Q_2 > Q_3 \)
Show Solution
The Correct Option is A
