Five phases. There are five known phases, or states, of matter: solids, liquids, gases, plasma and Bose-Einstein condensates. The main difference in the structures of each state is in the densities of the particles. Solids. In a solid, particles are packed tightly together so they are unable to move about very much. read more
Quick Answer. The five states of matter include Bose-Einstein condensates, solids, liquids, plasmas and gases. Matter is anything that occupies space and has weight. read more
The level of kinetic energy per molecule of gas is the second highest among all of the states of matter (first is plasma). On account of this high kinetic energy, gas atoms or molecules tend to freely bounce off any and all confining surfaces, as well as one another. read more
