Question

# An ideal gas us 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 temperature of the gas are $$P_2, V_2$$ and $$T_2$$ respectively. For this expansion

A
q=0
B
T2=T1
C
P2V2=P1V1
D
P2Vγ2=P1Vγ1

Solution

## The correct options are A $$q=0$$ B $$T_2=T_1$$ C $$P_2V_2=P_1V_1$$Chemistry
