heterogeneous mixtures
Introduction
What is Chemistry?
1-Chemistry: is the study of matter
and its transformations.
It's important to learn chemistry if
you are studying any branch of science
because all branches of science involve
matter and the interactions between
types of matter. Students wanting to
become doctors, nurses, physicists,
dentists, pharmacists, and (of course)
chemists all must study chemistry.
2. Matter
Any thing that has a mass and occupies
volume.
States of matter:
i. Solid
ii. Liquid
rigid
fluid
fixed shape no fixed shape
fixed volume fixed volume
iii. Gas
fluid
no fixed shape
no fixed volume
gas
liquid
solid
► Matter can undergo physical or
chemical changes:
Physical change
*Change of state where each
substance
*Retains its chemical identity.
e.g1. (ice  water  vapor)
e.g 2. sugar dissolving in water
Chemical change
Change in chemical identity.
e.g1. rust of iron
e.g2. hydrogen burns in
air to form water
Properties of matter: there are 2 types of properties:
Properties of matter: there are 2 types of
properties:
1-Chemical properties
Properties that describe how a substance
changes into a completely different substance
(corrosion, oxidation are examples of
chemical properties).
2- Physical properties
Properties that can be observed without
changing the composition of the substance
(color, density, m.p., b.p., hardness are
examples of physical properties).
Physical properties are classified into:
Melting point:
Point at which the solid becomes
liquid.
Boiling point:
Temperature at which the liquid
becomes gas.
Density:
Weight per unit volume, density =
(mass/volume)
Solubility:
Amount of material that will dissolve
in solvent and produce stable solution.
Example for Homogenous mixture
soft drink, milk
Example for Heterogeneous mixture
cement,
iron filings in sand
