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 filled at pressure 2 atm and temp of 300 K , in a balloon is kept in vaccum with in a large container wall of balloon is punchtured then container temperature :
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
An insulated container is divided into two equal portions. One portion contains as ideal gas at pressure P and tenperature T . The othe portion is a perfect vaccume. If a hole is opened between the two portions, claculate a. the change in internal energy. b. the change in temperature.
Gases excert pressure on the walls of the container , because the gas molecules
A sample of gas in a box is at pressure P_0 and temperature T_0 . If number of molecules is doubled and total kinetic energy of the gas is kept constant, then final temperature and pressure will be
Some ideal monoatomic gas A in an enclosure has a pressure P and the temperature T . Another ideal monoatomic gas B enclosed in a container of the same volume has a pressure of 2P and temperature T/2 . The ratio of the average kinetic energy per molecule of gas A to gas B is
A sample of an ideal gas occupies a volume V at pressure P and absolute temperature T. The masss of each molecule is m, then the density of the gas is
A container having 3 mole of ideal gas occupies 60 litres at pressure P and temperature T. If 0.1 mole of gas is introduced at same P and T in container the change in volume will be ________ litre.
