Kinetic theory of gases is a generalization offered by Maxwell, Boltzmann, Clausius, etc., to explain the behavior of ideal gases. This theory assumes that ideal gas molecules neither attract nor repel each other. Average kinetic energy of gas molecules is directly proportional to the absolute temperature. A gas equation called kinetic gas equation was derived on the basis of kinetic theory
Pick up the correct statement/statements: 1. gas A will tend to lie at the bottom. 2. the number of atoms of various gases A, Band Care same. 3. the gases will diffuse to form homogeneous mixture, 4. average kinetic energy of each gas is same,

The essential conditions for liquefaction of gases were discovered by Andrews in 1869 as a result of his study of pressure-volume-temperature relationship for 
, It was found that above a certain temperature, it was impossible to liquefy a gas whatever the pressure was applied. The temperature below which the gas can be liquefied by the application of pressure alone is called critical temperature 
. The pressure required to liquefy a gas at this temperature is called the critical pressure 
The volume occupied by one m91e of the substance at the critical temperature and pressure is called critical volume. Critical constants are related with van der Waals' constant as follows:
Which of the above gases cannot be liquefied at 100 K and 50 - atm?
