Answer in one word/a few words.

The theory states that matter is made up of small particles

Answer 1

The kinetic theory of matter:

• The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion.
• The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
• All the particles should possess energy, and the energy of the particles depends on the temperature, which determines the existence of the substance in a solid, liquid, or gas state.
