Question

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,

Since container is thermally insulated. So, q = 0, and it is a case of free expansion therefore W = 0 and ∆ E = 0 So, T 1 = T 2 Also, P 1 V 1 = P 2 V 2
