Change of State. Matter can move from one state to another, but can still be the same substance. A change of state, also called a phase change, is a physical change from one state of matter to another, for example, from solid to liquid or from liquid to gas.
Whether its physical state is a solid (ice), a liquid (water), or a gas (vapor), it's still water made up of H 2 O molecules. Solids have a particular size and shape. The atoms and molecules in a solid are packed together tightly and do not move much. Common examples of solids are an orange, a rock, or a coin.
