### Question Asked by a Student from EXXAMM.com Team

Q 2626234171.     An ideal gas in 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
JEE 2014
