Question

# An ideal gas in thermally insulated vessel at internal pressure =P1. volume =V1 and absolute temperature =T1 expands irrversibly 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.

Solution

## The correct options are A q=0 B T2=T1 C P2V2=P1V1 Since the vessel is thermally insulated hence, q=0 Work done w=0 is zero for free expansion . ΔU is also zero for free expansion , so T1=T2,and PV= constant ( isothermal process )
