An ideal monoatomic gas is confined in a horizontal cylinder by a spring-loaded piston (as shown in the figure). Initially, the gas is at temperature T1, pressure p1 and volume v1 and the spring is in its relaxed state. The gas is the heated very slowly to temperature T2, pressure p2 and volume v2. During this process, the piston moves out by a distance x. Ignoring the friction between the piston and the cylinder, then choose the correct statements.

If V2=2V1 and T2=3T1, then the energy stored in the spring is 1∕4(p1V1).
If V2=2V1 and T2=3T1, then the change in interval energy is 3p1V1
If V2=3V1 and T2=4T1, then the work done by the gas is
7
3
p1v1
If V2=3V1 and T2=4T1, then the heat supplied to the gas is
1
4
(p1v1)
