STATE CHANGE GRAPH

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

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.

HETEROGENEOUS MIXTURES
Are made up by two or more substances at not fixed proportions They can be separated by physical methods MATTER A sample of matter that consists of only one component. PURES SUBSTANCES MIXTURES HOMOGENEOUS MIXTURES HETEROGENEOUS MIXTURES COMPOUNDS SIMPLE SUBSTANCES They are made up by two or more elements combined in a fixed proportion The properties of a compound are completely different that their elements. We can break down by chemical means They have uniform composition and properties throughout We cannot see their components with a naked eye They do not have uniform composition and properties throughout We can see their components They are made up by atoms of the same element We cannot break down in any way
