The pressure versus volume graph for an ideal gas of equal number of moles at different temperature are plotted as shown in the figure. Choose the correct alternative:

image $(A) T_1 \gt T_3$ $(B) T_1 \lt T_3$ $(C) T_1 = T_3$ $(D)$ Unable to compare $T_1$ and $T_3$

1 Answer

Since pt. 1 and pt. 3 are at the same pressure, they can be compared only by comparing their volumes.
Since $V_3 \gt V_1 \rightarrow T_3 \gt T_1$
Note: We cannot say anything about the type of process the gas is undergoing just by looking at the graph.
