An ideal gas is at pressure P and temerature T in a box, which is kept in vaccum with in a large container. The wall of the box is punctured. What happens as the gas occupies entire container?
A
It's temperature falls
B
Its temperature rises
C
Its temperature remains the same
D
Unpredicatable
Text Solution
Verified by Experts
The correct Answer is:
C
`w=-PDeltaV=0` `DeltaU=q+w=0` Temperature remains constant.

An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_1 . The same gas is expanded adiabatically to a volume 2V, the final pressure is P_A . In terms of the ratio of the two specific heats for the gas gamma , the ratio P_I//P_A is :
Pressure of an ideal gas in container is independent of shape of the container explain.
Two containers, each of volume V_0 , joined by a small pipe initially contain the same gas at pressure P_0 and at absolute temperature T_0 . One container is now maintained at the same temperature while the other is heated to 2 T_0 . If the number of moles of gas in the container at temperature 2T_0 is (nP_0 V_0)/( 3 RT_0) then 'n' is
A gas of temperature T_0 is enclosed in a container whose walls are (initially) at temperature T. Now, the gas exerts a higher pressure on the walls of the container when
The pressure exerted on the walls of the container by a gas is due to the fact that gas molecules are
When the temperature of a gas in a rigid container is raised, the pressure exerted by the gas on the walls of the container increases because
