Short Answer TypeWhat are the main postulates of Kinetic energy Molecular Theory of liquids?
A liquid state is regarded as a condensed gas or a molten solid. The following are the postulates of kinetic molecular theory of liquids:
1. A liquid is made up of small particles called molecules and these molecules have restricted random motion.
2. The molecules are quite close to each other.
3. There are appreciable attractive forces between the molecules.
4. The average kinetic energy of the molecules in a liquid is proportional to its absolute temperature.

(i) Volume (ii) Density
(iii) Compressibility (iv) Diffusion?
