Kinetic Theory of Matter; States of Matter

The Kinetic Theory of Matter explains what matter is made up of and what the particles in the matter does. Atoms are composed to tiny, different particles such as atoms, ions, and molecules. The particles are in constant, random motions. Particles collide with each other in the walls of the container in which they are held. 

There are 3 states of matter, solid, liquid, and gas. Solids have a definite value and definite shape. Liquids have a definite volume but not a definite shape. Gases have no definite value and no definite shape. These are the 3 difference between solids, liquids, and gases. 

There is also a 4th state of matter which is plasma. Plasma is a hot ionized material that is contained with nuclei and electrons. 

Can a solid turn into a gas and skip the liquid stage? Yes it can, it's called sublimation. Sublimation is when a solid turns straight to a gas like dry ice. Dry ice is -72 degrees Fahrenheit that it can turn into a gas without being a liquid. I never knew that the theory and states of matter could be so interesting!
