Question

What do you mean by kinetic theory of matter?

Answer 1

1. Kinetic theory of matter: The kinetic theory of matter states that matter should be made up of particles that must be in constant motion.
2. The matter is made of tiny particles called molecules. These molecules continuously move, so they possess kinetic energy.
3. When the temperature of matter is increased, the kinetic energy of the molecules increases. Hence, the kinetic energy is directly proportional to temperature.
4. Hence, kinetic theory helps to determine the existence of the substance in a solid, liquid, or gas state.
