Question

dicuss the kinetic theory of matter.

Answer 1

According to kinetic theory of matter, matter is composed of small particles – atoms or molecules which are always moving.

Assumptions of kinetic theory are:

1) Matter consists of small particles

2) Separation between particles of matter

• There is large separation between particles of gases and there are no attractive or repulsive forces between the molecules.
• The particles in liquid are also far but close as compared to gases.There exists attractive forces between the particles.
• The particles in solids are tightly packed and he forces of attraction confine the solid to a specific shape.

3) Particles of matter are in a constant motion.

4) The particles of matter often collide with each other.
