Q. The adjoining figure shows graph of pressure and volume of a gas at two temperatures $T_{1}$ and $T_{2}.$ Which of the following inferences is correct
A) $T_{1} > T_{2}$
B) $T_{1} = T_{2}$
C) $T_{1} < T_{2}$
D) No interference can be drawn
Explanation
(c) For a given pressure, volume will be more if temperature is more [Charle’s law]

From the graph it is clear that $V_{2} > V_{1} \Rightarrow T_{2} > T_{1}$
