How will you justify the following postulates of the kinetic theory of gases ?
(i) Molecules in a gas follow zig-zag path.
(ii) Collisions among the gas molecules are of elastic nature.
(iii) There are no forces of interaction among the gas.

Why do molecules in a gas follows zig-zag path ?

How will you justify that the collision among the gas molecules are perfectly elastic?

In kinetic theory of gases, which of the following statements regarding elastic collisions of the molecules is wrong ?

According to the kinetic theory of gases, in an ideal gas, between two successive collisions, a gas molecule travels

The collision taking place among gas molecules depends upon

The kinetic theory of gases presumes the collisions between the molecules to be perfectly elastic because the collisions between molecules of a gas:

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.

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.

One of the assumptions of kineti theory of gases is that there is no force of attraction between the molecules of a gas. State and explain the evidence that shows that the assumption is not applicable for real gases.

How would you account for the following : (i) The metallic radii of the third (5d) series of transition metals are virtually the same as those of the corresponding group members of the seconds (4d) series. (ii) There is a greater range of oxidation states among the actinoids than among the lanthanoids.
