He, N2 and O3 are expanded adiabatically and their expansion curves between log P and log V are plotted under similar conditions. About the ratio of the slopes, which one is not correct :
1
the ratio of slopes of log P vs log V curves for He and O3 is 1.28
2
the ratio of slopes of log P vs log V curves for He and N2 is 1.19
3
the ratio of slopes of log P vs log V curves for N2 and O3 is 1.05
4
the slope of He is least steeper and for O3 is most steeper
