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

Molecular attraction and size of the molecules in a gas are negligible at :

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.

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 .

Real gases approches ideal gas at high temperature and low pressure because A) interatomic separation is large size of the molecule is negligible when compareed to inter atomic separation

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.
