Comment on the statements :
(i) Molecular volume in a gas can be neglected as compared to the total volume of the gas.
(ii) Forces of attraction and repulsion among the gas molecules are negligible.

Molecular attraction and size of the molecules in a gas are not negligible at

The gas molecule can be liquefied and solidified due to the pressure of ...... Force of attraction.

For the non-zero value of the force of attraction between gas molecules, gas equation will be

Does co-volume represent the actual volume of the molecules in a gas ?

Is the excluded volume of a real gas equal to the actual E volume of the molecules of a gas ?

For the non-zero volume of the molecules, real gas equation for n mol of the gas will be

Which one of the following is not an assumption in the kinetic theory of gases? a) The volume occupied by the molecules of the gas is negligible. b) The force of attraction between the molecules is negligible. c) The collision between the molecules are elastic. d) All molecules have same speed.

The S.I. unit of volume of gas is measured in

The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory . These are (i) there is no force of attraction between the molecules of a gas (ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas (iii) particles of a gas are always in constant random motion .

The ratio of excluded volume ( b ) to molar volume of a gas molecule is
