The three main points of the kinetic theory of matter are all matter consists of molecules and atoms; these molecules and atoms are constantly in motion; and as the temperature increases, the speed of the particles, and therefore the energy of the matter, increases. Each of these three points, once further explained, reveal how and why matter can change between the three phases of solid, liquid and gas.Continue Reading
All matter, regardless of its chemical makeup, has three states: solid, liquid, and gas. Matter alternates between these three states as its temperature increases and its particles accelerate. When the particles of matter accelerate, the space between them also increases, which alters the properties of the same element of matter in each of its three states.
The three main points of the kinetic theory of matter explain why matter in each state behaves in a different manner when placed in a container:
