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`

B

`p/2, T/2`

C

p,T

D

`p,T/2`

Text Solution

Verified by Experts

The correct Answer is:
A
Internal energy of the gas remains constant, hence
`T_(2)=T`
Using `p_(1)V_(1) = p_(2)V_(2), pV/2 =p_(2)V` or `p_(2) =p/2`

A nonconducting cylinder having volume 2 V_(0) is partitioned by a fixed non conducting wall in two equal part. Partition is attached with a valve. Right side of the partition is a vacuum and left part is filled with a gas having pressure and temperature P_(0) and T_(0) respectively. If valve is opened find the final pressure and temperature of the two parts.

An insulated container of gas has two chambers separated by an insulating partition. One of the chmabers has volume V_1 and contains ideal gas at pressure P_1 and temperature T_1 .The other chamber has volume V_2 and contains ideal gas at pressure P_2 and temperature T_2 . If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be

A container of volume 1m^3 is divided into two equal parts by a partition. One part has an ideal gas at 300K and the other part is vacuum. The whole system is thermally isolated from the surroundings. When the partition is removed, the gas expands to occupy the whole volume. Its temperature will now be .......
