States of Matter and Phase Changes
Matter can be found as solids, liquids, gasses, plasmas, and even Bose-Einstein condensates. What makes each of the phases of matter different is how the molecules react to their kinetic energy and the strength of the molecular bonds. As kinetic energy (measured as temperature) goes up, the ability of the bonds to hold the molecules together is less and less, and eventually, the matter will change state—solids melt into liquids, liquids vaporize into gases, and gases ionize into plasmas. If kinetic energy goes down, the reverse happens.
