A container of volume `1m^(3)` is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at 300 K . The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be

A

300 K

B

239 K

C

200 K

D

100 K

Text Solution

Verified by Experts

The correct Answer is:
A
For free expansion - `Delta W=0, Delta U=0`
So temperature remains same i.e., 300 K.

A rigid and insulated tank of 3m^(3) volume is divided into two compartments. One compartment of volume of 2m^(3) contains an ideal gas at 0.8314 Mpa and 400 K while the second compartment of volume of 1m^(3) contains the same gas at 8.314 Mpa and 500 K. If the partition between the two compartments is rptured, the final temperature of the gas is :

A container of volume 2L is seperated into equal compartments. In one compartment, one mole of an ideal monoatomic gas is filled at 1 bar pressure and the other compartment is completely evacuted. A pihole is made in the seperator so gas expands to occupy full 2 L and heat is supplied to gas so that finally pressure of gas equals 1 bar. Then :

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 container is divided into two compartments. One compartment contains 2 moles of N_(2) gas at 1 atm and 300 K and other compartment contains H_(2) gas at the same temperature and pressure. Volume of H_(2) compartment is four times the volume of N_(2) compartment [Assuming no reaction under these conditions] Calculate the final total pressure if partition between two compartments is removed.
