The volume V versus temperature T graphs for a certain amount of a perfect gas at two pressures P1 and P2 are as shown in the figure. It can be concluded that
1
the pressure P1 is greater than the pressure P2
2
the adiabatic index for P1 is higher than that for P2
3
P1 represents monoatomic gas and P2 represents diatomic gas
4
P2 represents monoatomic gas and P1 represents diatomic gas
