For this question use 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 molecular collisions are perfectly elastic.
4. increase in temperature increases the kinetic energy of the molecules.
which of the above assumptions accounts for the compressibility of gases as compared to liquids and solids?
