A container A contains an ideal gas at pressure ‘P’, volume ‘V’ and temperature ‘T”. A second container ‘B’ contains the same gas at pressure ‘2P’, volume ‘2V’ and temperature ‘T/2’. The ratio of mass of gas in A to that in B is

If one mole of an ideal gas Ɣ= 5/3 is mixed with one mole of a diatomic gas Ɣ=7/5 The value of ‘ Ɣ ‘ for the mixture is

A jar ‘P’ is filled with a gas by parameters P, V and T, V another jar ‘Q’ filled with a gas with parameters 2P, V/4 and 2T, where the symbols have their usual meanings. The ratio of number of molecules of jar ‘P’ to those of jar ‘Q’ is

In a vessel, the ideal gas is at pressure ‘P’. If the mass of all the molecules is halved and their speed is doubled, then the resultant pressure will be

The average force applied on the walls of a closed container depends on Tx where ‘T” is the temperature of an ideal gas. The value of ‘x’ is

The translational kinetic energy of the molecule of a gas at absolute temperature (T) can be doubled by

At constant temperature, the pressure of gas is decreased by 20%. The percentage change in volume
