WebbPhase Changes. There are forces of attraction and repulsion that exist between molecules of all substances. These intermolecular forces allow molecules to pack together in the solid and liquid states. When a pot of water is placed on a burner, it will soon boil. A phase change is occuring; the liquid water is changing to gaseous water, or steam. Webb•Matter exists in one of the three phases: solid, liquid or gas. The transition of matter from one phase to another is known as a phase change. 2 What is Phase Change? •Phase change generally occurs at a constant temperature when the pressure is constant.
