7. PHYSICAL PROPERTIES OF MATTER
- Properties that can be identified by our five senses or measuring tools
Handle is made of
heat insulator
such as plastic
Pan is made of
heat conductor
such as steel
8. PHYSICAL PROPERTIES OF MATTER
- Properties that can be identified by our five senses or measuring tools
Different liquids have
different boiling
points
Melting point of ice is the
temperature at which ice changes
into liquid at certain temperature
9. PHYSICAL PROPERTIES OF MATTER
- Properties that can be identified by our five senses or measuring tools
Sugar can dissolve in coffee
10. 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

33. DIFFUSION
Process in which the
particles of substances
diffuse from high
concentration area
to a low
concentration area
34. IN A SOLID
Rate of diffusion of particles isslow
OBSERVATION
Gel turns
blue after a
few days
35. IN A LIQUID
Rate of diffusion of particles higher thaninsolid
OBSERVATION
Water turns
purple after
two hours
36.
37. IN A GAS
Rate of diffusion of particles isthe highest
OBSERVATION
Brown colour
bromine vapour
spreads evenly
throughout the
gas jar in a few
minutes
