· MATTER

- EXIST AS THREE STATES.

- CHEMICAL PROPERTIES DESCRIBE A SUBSTANCE TO UNDERGO A CHANGE TO A DIFFERENT SUBSTANCE

- PHYSICAL PROPERTIES DESCRIBES ONLY PHYSICAL CHARACTERISTICS AS LONG AS NO CHEMCIAL CHANGE OCCURS.

· PHYSICAL CHANGE

- PHYSICAL CHANGE INVOLVES A CHANGE IN ONE OR MORE PHYSICAL PROPERTIES, BUT NO CHANGE IN COMPOSITION.

- CHEMCIAL CHANGE TRANSFORMS A SUBSTANCE INTO A NEW SUBSTNANCE.

· MIXTURE

- HAS VARIABLE COMPOSITION.

- HOMOGENEOUS MIXTURE HAS SAME PROPERTIES THOUGHOUT.

- HETEROGENSOU MIXTURE DOES NOT HAVE THE SAME PROPERTIES THROUGHOUT,

- DISTILLATION AND FILTRATION CAN PHYSICALLY SEPARATE MIXTURES.

· PURE SUBSTANCE

- PURE SUBSTANCES ARE OF TWO TYPES.

- ONE TYPE IS AN ELEMENT WHICH CAN BE BORKEN DOWN INTO SIMPLER SUBSTANCES.

- THE SECOND TYPE IS A COMPOUND WHICH CA BE BROKEN DOWN CHEMCILALL Y INTO ELEMENTS.
