Question

A container with insulating walls is divided into two equal parts by a partition fitted with a valve. 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
A. `(P)/(2),(T)/(2)`
B. `P,T`
C. `P,(T)/(2)`
D. `(P)/(2),T`

Answer 1

Correct Answer - D

It is the free expansion
So, `T` remain constant
`P_(1)V_(1) = P_(2)V_(2)`
`P (V)/(2) = P_(2)(V)`
`P_(2) = ((P)/(2))`
