A gas in a cylinder is at pressure P. If the masses of all the molecules are made one third of their original value and their speeds are doubled, then find the resultant pressure.

If the masses of all the molecules of a gas are doubled and their speed are havled, then the ratio of the final and initial pressures will be

If masses of all molecules of a gas are halved and the speed doubled. Then the ratio of initial and final pressure is :

For a given mass of gas, velocities of all the molecules are ____ even when bulk parameters like pressure, volume and temperature are fixed.

A diatomic gas at pressure P and volume V is compressed adiabatically to frac(1)(32) times the original volume. Find the final pressure.

Three containes of the same volume contain three different gases. The masses of the molecules are m_(1), m_(2) and m_(3) and the number of molecules in their respective containers are N_(1), N_(2) and N_(3) . The gas pressure in the containers are P_(1), P_(2) and P_(3) respectively. All the gases are now mixed and put in one of the containers. The pressure P of mixture will be

An ideal gasin a cylinder is compressed adiabatically to one-third its original volume. During the processif 45 J of work is done on the gas by the compressing agent, what is the change in internal energy?

The density of a certain mass of a gas at STP is d . If the pressure of the gas is doubled and the temperature is made one-third of its initial value, the new density will be

A given sample of an ideal gas occupies a volume V at a pressure p and absoulte temperature T.The mass of each molecule of the gas is m. Which of the following gives the density of the gas ?

At pressure P and absolute temperature T a mass M of an ideal gas fills a closed container of volume V. An additional mass 2M of the same gas is added into the container and the volume is then reduced to V/3 and the temperature to T/3 . The pressure of the gas will now be:

Consider two containers A and B containing identical gases at the same pressure , volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically . The ratio of final pressure of gas in B to that of gas in A is
