Question

How do scientists use the kinetic theory of matter?

Answer 1

The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter.

• If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid.

• If particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid.

• If particles have enough kinetic energy to completely overcome the force of attraction between them, matter exists as a gas.

Answer 2

Explanation: The kinetic theory of matter states that everything that matter consist of are in the constant motion. It is used by scientist to explain the different phases of matter that is solid, liquid and gas. It is also used by them to explain the flow of energy in the matter such as heat and electric current. The kinetic theory of matter is also illustrated by the process of diffusion.
