The following are the main assumptions of the Kinetic Molecular Theory of gases:

  1. Gases are made up of molecules which are relatively far apart.
  2. The molecules are in motion at high speeds.
  3. The molecules are perfectly elastic.
  4. Increase in temperature increases the kinetic energy of the molecules.

The assumption that accounts for the great compressibility of gases compared to liquids and solids is:



1

2

3

4

none of the above

Charles law has to do with volume and temperature, right? So, the only one of the assumptions that deals with temperature is #4.

Answer: The correct statement is Statement 1.

Explanation:

The assumptions of kinetic molecular theory of gases are given in the question and we need to find the assumption that correctly describes the great compressibility of gases as compared to liquids and solids.

Compressibility is defined as the property of matter by which the particles of matter can be brought closer to each pother.

As, the intermolecular spacing between the particles of gases is more, it can be bought together more than the solid or liquid by applying pressure.

Hence, this assumption very well accounts for the great compressibility of gases.
