(D) According to Charles's Law,for a fixed mass of gas at constant pressure,$V \propto T$,which can be written as $V = (nR/P)T$.Comparing this with the equation of a straight line $y = mx$,where $y = V$ and $x = T$,the slope $m = nR/P$.Since the slope is inversely proportional to pressure $(m \propto 1/P)$,the line with the smallest slope corresponds to the highest pressure.From the given graph,the slope of the line for $P_3$ is the smallest,followed by $P_2$,and the slope for $P_1$ is the largest.Therefore,the relationship between the pressures is $P_3 > P_2 > P_1$.

For a fixed mass of an ideal gas,the following graph is given. Determine the correct relationship between $P_1, P_2$ and $P_3$.
