An ideal gas in a thermally insulated vessel at internal pressure=P1, volume=V1 and absolute temperature =T1 expands irreversibly against zero external pressure as shown in the diagram. The final internal pressure, volume and absolute temperature of the gas are P2, V2 and T2, respectively. For this expansion which of the following relation(s) holds true?

1.	An ideal gas in a thermally insulated vessel at internal pressure=P1, volume=V1 and absolute temperature =T1 expands irreversibly against zero external pressure as shown in the diagram. The final internal pressure, volume and absolute temperature of the gas are P2, V2 and T2, respectively. For this expansion which of the following relation(s) holds true?
Answer» An ideal gas in a thermally insulated vessel at internal pressure $= P_{1}$ , volume $= V_{1}$ and absolute temperature $= T_{1}$ expands irreversibly against zero external pressure as shown in the diagram. The final internal pressure, volume and absolute temperature of the gas are $P_{2}, V_{2}$ and $T_{2}$ , respectively. For this expansion which of the following relation(s) holds true?
