The postulates of kinetic theory of gases.
a) Particles of matter have spaces between them and these spaces are called intermolecular spaces. Intermolecular spaces depend on the intermolecular force of attraction between the particles, therefore, these spaces are different in solids, liquids, and gases. In solids intermolecular spaces are very less or negligible, liquids have moderate intermolecular spaces and gases have the highest intermolecular spaces.
b) Particles of matter attract each other with a force of attraction called intermolecular force of attraction. The intermolecular force of attraction depends upon the distance between the particles, the higher the distance between the particles, the lesser will be the force of attraction and the lesser the distance between the molecule, the higher will be the force of attraction. The intermolecular force of attraction is highest in solids, moderate in liquids and least in gases.
C) The energy posses by the molecules depends on the random motion of particles. Since gases have the weakest intermolecular force of attraction, therefore, molecules can move easily and gain kinetic energy. Therefore gases have high energy.
