6  Vaporization: is the state change from liquid to gas.  Evaporation: is the state change from liquid to gas. It happens at room temperature and only on the surface of the liquid. The rate of evaporation increases when the temperature increases.  Boiling (also called ebullition): is the state change from liquid to gas at a constant temperature. All the liquid changes state and while it happens, the temperature doesn ’ t change.  Condensation : is the state change from gas to liquid.  Boiling point: is the temperature at which a liquid boils. It is different for each substance. Boiling point = Condensing point

7  Freezing: Is the state change from liquid to solid.  Melting: Is the state change from solid to liquid.  Melting point: Is the temperature at which a solid turns into a liquid. It is different for each substance. Melting point = Freezing point  Sublimation: Is the transition from solid to gas.  Deposition: Is the state change from gas to solid.

15  Sieving: Consists of separating larger pieces of something from smaller pieces.  Magnetization: separating a substance, like iron, using a magnet.  Filtering: method of separation that is used for separating insoluble solids from liquids.  Decanting: consists of separating two immiscible liquids of different densities.  Crystallization: Process that consists of obtain a solid dissolved in a liquid by evaporation of liquid.  Distillation: is a method of separating substances based on differences in their boiling points. This method is used to separate a liquid from the solution. The other components can be solids or liquids.
