Ppt Phase Changes Powerpoint Presentation Free Download Id 2437650 Presentation transcript. phase changes • matter exists in three physical states: • solid • liquid • gas • when matter is converted from one physical state to another, a phase change occurs. • a change in the physical state of a substance. phase changes • in order for a phase change to occur, the molecules must gain enough kinetic. Freezing • phase change from a liquid to a solid • molecule slow down, move closer together and release heat energy. vaporization (boiling) • phase change from a liquid to gas. it occurs at the boiling point of matter. • molecules speed up, move farther apart, and absorb heat energy.

A phase change is the reversible physical change. that occurs when a substance changes from one. state of matter to another. melting, freezing, vaporization, condensation, sublimation, and deposition are six common phase. changes. 3. temperature and phase changes. the temperature of a substance does not change. The document discusses phase changes between solid, liquid, and gas phases. it defines latent heat as the heat absorbed or released during a change of state without a change in temperature, such as the heat of fusion absorbed during melting or the heat of vaporization absorbed during boiling. Phase change. matter can change from one phase to another. this is called a phase change; 4 phase changes. the amount of heat energy in any particular piece of matter can change. a big enough change in heat energy causes a phase change. solids liquids gas ; there are different names for each of the phase changes. add heat energy. add energy. 5.
