PRESENTATION OUTLINE

COMPRESSIBLE

Capable of being compressed.

COMPRESSIBLE

THE PROCESS OF CHANGING SOMETHING FROM A SOLID INTO A LIQUID.

MELTING

The process through which a substance changes from a liquid to a solid.

FREEZING

The process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.

EVAPORATION

The process by which water vapor in the air is changed into liquid water.

CONDENSATION

When anything solid turns into a gas without first becoming liquid.

SUBLIMATION

A change in which no new substances are formed.

PHYSICAL CHANGE

Usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance.

CHEMICAL CHANGE

Is an insoluble solid that emerges from a liquid solution.

PRECIPITATE

Substances that are made of only one type of atom or molecule.

PURE SUBSTANCE

Is a material made up of two or more different substances which are mixed.

MIXTURE

Simply any mixture that is uniform in composition throughout.

homogeneous mixture

Is a combination of two or more pure substances in which the original substances retain their chemical properties.

heterogeneous mixture

Any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

FILTRATION

The separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates.
