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.
