WHAT IS THE NATURE OF MATTER AND ITS CHARACTERISTICS

MLS 1-D

MATTER IS ANYTHING THAT OCCUPIES SPACE AND HAS MASS

EXIST IN THREE PHYSICAL STATES

SOLIDLIQUIDGAS

SOLIDSPARTICLES ARE HOLD VERY CLOSENOT MUCH FREEDOM OF MOVEMENTHAVE DEFINITE VOLUME AND SHAPE

LIQUIDPARTICLES ARE CLOSE TO EACHOTHER BUT,CAN MOVE AROUNDHAVE DEFINITE VOLUME BUT, NO DEFINITE SHAPE

GASPARTICLES ARE FAR APARTMOVEMENT IS EASY AND FASTNO DEFINITE VOLUME, NO DEFINITE SHAPE

CLASSIFICATION OFMATTER

Ahomogeneous mixtureis a mixture where the components that make up the mixture are uniformly distributed throughout the mixture.

EX.: air, blood, saturated sugar water

Aheterogeneous mixtureis a mixture where the components of the mixture are not uniform or have localized regions with different properties.

EX.: rocks, oil and water, soup, pizza

A PURE SUBSTANCE IS ANY KIND OF HOMOGENOUS MATTER WITH PROPERTIES THAT CANNOT BE CHANGED BY FURTHER PURIFICATION.

EX.: ELEMENTS AND COMPOUNDS ELEMENTS-SUBSTANCE IN WHICH MOLECULES ARE MADE UP OF ONLY ONE KIND OF ATOM.

COMPOUNDS-SUBSTANCE COMPOSED OF TWO OR MORE DIFFERENT ELEMENTS THAT ARE CHEMICALLY COMBINED.

MIXTURE IS A PHYSICAL COMBINATION OF TWO OR MORE SUBSTANCE IN ANY PROPORTIONS AND IN WHICH EACH SUBSTANCE RETAINS ITS OWN CHEMICAL IDENTITY.IT MAY BE EITHER HOMOGENOUS OR HETEROGENOUS.THE COMPONENTS OF A MIXTURE CAN BE SEPARATED IN PHYSICAL MEANS. SUCH AS, DECANTATION, FILTRATION, DISTILLATION, EVAPORATION, SUBLIMATION, AND THE USE OF A MAGNET.
