5.1 WHAT IS A MATTER?

Substance that has mass
and occupies space

Almost Living things
everything Non-living thing
In nature is
a matter

Use a pin to prick
the balloon

Air has mass and

occupies space

solid has mass
and

occupies
space

PHYSICAL PROPERTIES OF MATTER

- Properties that can be identified by our five senses or measuring tools

Pan is made of Handle is made of
heat conductor heat insulator
such as steel such as plastic

PHYSICAL PROPERTIES OF MATTER

- Properties that can be identified by our five senses or measuring tools

Different liquids have Melting point of ice is the
different boiling
temperature at which ice changes

points into liquid at certain temperature

PHYSICAL PROPERTIES OF MATTER

- Properties that can be identified by our five senses or measuring tools

Sugar can dissolve in coffee

CHEMICAL PROPERTIES OF MATTER

- Properties that become evident when it changes to a new substance

Rusting occurs on iron
when it is exposed to
water and air

CHEMICAL
PROPERTIES

OF MATTER

- Properties that
become evident
when it changes
to a new
substance

HOW CAN WE CLASSIFY density
MATERIALS BY THEIR
DIFFERENT CHARACTERISTICS?

solubility Melting point
and boiling
point

1.

density

lower density →float,
higher density →sink

2. Melting point and boiling point

Ice melts
at 0oC

Iron melts at 1536oC water boils
at 100oC

3.

solubility

Ability of
substance to
dissolve in a
given amount of
solvent to form a

solution

Solubility → depends
on the physical and
chemical properties of
its solute and solvent

Chemical properties are the properties of a substance that
become evident when it changes to a new substance Physical properties are the properties that can be identified by

using our five senses
or measuring tools. Physical properties of matter depend on
the type of material it is
made of
