The pressure p of gas is plotted against its absolute temperature T for two different constant volumes, V1 and V2. When V2 > V1, the
1
Curves have the same slope and do not intersect
2
Curves must intersect at some point other than T = 0
3
Curve for V1 has a greater slope than that for V2
4
Curve for V2 has a greater slope than that for V1
