The pressure P for a gas is plotted against its absolute temperature T for two different volumes $V_1\: and \: V_2$ where $V_1 > V_2$ . If P is plotted on $y$ - axis and T on $x$ - axis then :

Question

$\begin {array} {1 1} (a)\;\text{The curve for $V_1$ has greater slope than that for $V_2$} \\ (b)\;\text{The curve for $V_2$ has greater slope than that for $V_1$} \\ (c)\;\text{Both curves have same slope} \\ (d)\;\text{The curves intersect at some point other than T = 0 }\end {array}$
