One part is filled with an ideal gas at a pressure P and temperature T, whereas the other part is completely evacuated. If the valve is suddenly opened, the pressure and temperature of the gas will be:                                    [AIEEE 11-05-2011]

A) \[\frac{P}{2},\frac{T}{2}\]                    

B) \[P,T\]

C) \[P,\frac{T}{2}\]                       

D)      \[\frac{P}{2},T\]

Correct Answer: D

Solution :

[d]

It is the free expansion

So, T remain constant
