The three fundamental phases of matter are solid, liquid, and gas (vapour), but others are considered to exist, including crystalline, colloid, glassy, amorphous, and plasma phases. When a substance undergoes a phase transition (changes from one state of matter to another) it usually either takes up or releases energy. baking a cake, burning wood, etc. Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed.. For example, the physical properties of ice, liquid water, and steam are quite different even though they are all H X 2 O \ce{H2O} H X 2 O and there is no difference in the molecular structure of the substances..

Create your account. It leads to more temperature, pressure or energy but that can change the matter. Matter exists as solids, liquids, gases, and plasma phases or states. Matter changes phase (called a phase transition) as a function of temperature and pressure. Going through a phase Adding or removing energy from matter causes a physical change as matter moves from one state to another.
