Chemistry
State the main postulates of the kinetic theory with special reference to -
(a) Inter-particle space
(b) Inter-particle attraction
(c) Energy possessed by particles of matter.
Answer
(a) Inter-particle space — The particles are arranged in a way such that, they have spaces between them. i.e. inter-particle space.
(b) Inter-particle attraction — All particles attract each other with a force which is
- maximum - if the particles are close to each other &
- minimum - if the particles are at a distance from each other.
(c) Energy possessed by particles of matter — Particles are in continuous motion and hence possess energy called Kinetic Energy. Application of heat increases Kinetic Energy of particles which then move more randomly.
