What are the characteristics/ particles of a solid ?
- definite shape
- definite column
- cannot be compressed
- cannot flow
What are the characteristics of a liquid ?
- No definite shape
- definite volume
- cannot be compressed

How many states of matter are there?
three
Name the three forms of matter?
- solids
- liquids
- gas
Can matter change state?
yes
How does a liquid turn into a gas?
Its heat until boiling point eg.water -steam
What is the boiling point of water?
100 degree Celsius
What is the opposite of boiling?
Condensing
What is diffusion?
diffusion is the movement of particles from an area of high concentration to an area of low concentration.
What is matter?
matter is anything that occupies space and has mass
What does evaporation mean?
evaporation is the changing of liquid to gas at the surface of the liquid
what is the result of the diffusion experiment
in the can of air freshener the particles are compressed in high concentration.
What is sublimation?
Sublimation is the transition from solid to gas state when heated eg dry ice
