What is kinetic theory?

• In chemistry, it explains that matter is composed of tiny particles that always in motion.

• The molecules are undergoes perfectly elastic collision with each other there is no loss of energy.
• According to this theory, the transfer of kinetic energy is heat.
• The kinetic theory of gases also tells us about thermodynamic behavior of gases. The  kinetic theory stated that temperature increases with increase in kinetic energy of particles or potential energy of the separation of the particles.
• It explained the physical property of the matter
