5. STATE CHANGE GRAPH

6. VOCABULARY: STATE CHANGES
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. VOCABULARY: STATE CHANGES
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. VOCABULARY: SEPARATING METHODS
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.
