Lesson 1: Properties of Matter

Chemistry

the study of matter, its composition, structure, properties, and the changes it undergoes.

What are the 4 states of matter?

Solid, Liquid, Gas, and Plasma.

Solid

definite shape and volume

Liquid

definite volume, no definite shape(depends on the container)

Gas

no definite shape or volume

Plasma

ionized gas

Physical Properties

happens without changing the composition of the susbtance, though their form may change. (color, viscosity, transparency, melting poin, boiling point, hardness, density, specific heat, and atomic or molecular diameter)

2 types of Physical Change

Intensive and Extensive

Intensive Properties

does not deped on the amount. (odor, taste, boiling point, melting point, retroactive index, density, electical conductivity, malleability, temparature, ductility, doffusion,)

Extensive Properties

(measured) amount, quality, size, mass, volume, length, width, height

What are the two types of mixtures?

Homogenous and Heterogenous

What are the characteristics of Homogenous Mixture?

the components are uniformly distributed throughout/ Elements in the misture cannot be distinguished through the naked eye

What are the characteristics of Heterogenous Mixture?

not uniformly distrubuted. You can see the individual substances in the mixture. (salad, halo-halo)

What methods can we use to separate components of mixtures and compounds?

FIltration, Decantation, Distillation, Mechanical Spearation, Centrifugation, Chromatography, Electrolysis
