1
Q
Matter?
A
Matter is everything that takes up space and has mass
2
Q
Mass?
A
Mass is the amount of matter in an object 
3
Q
What are the three states of matter?
A
Solid , liquid and gases
4
Q
All about liquids: e.g. water
A
- The particles can move and slide past each.
- forces are weaker than solids
- The particles vibrate more.
5
Q
All about solids: e.g. ice
A
- The particles are tightly packed together
- there are strong forces that hold them together
- they vibrate a little, but don’t move
6
Q
All about gases: e.g. steam
A
- The particles are separated from each other and move a lot.
- there are very weak forces between the particles
- The particles are always in motion and hit each other and the container.
7
Q
The properties of a solid;
A
- definite shape
- definite volume
- Difficult to compress
- do not flow
8
Q
Properties of a liquid;
A
- No definite shape
- definite volume
- difficult to compress
- flow easily
9
Q
Properties of gases;
A
- no definite shape
- No definite volume
- Easy to compress
- Diffuse to fill all available space
10
Q
Diffusion?
A
Diffusion is the movement of particles from high concentration to low concentration.
11
Q
Solid to a liquid =
Liquid to a solid =
A
- Melting
- freezing
12
Q
Liquid to a gas =
Gas to a liquid =
A
- Boiling
- Condensation
13
Q
Melting?
A
- Solid - liquid
- Melting point is when the temperature at which a solid changes to a liquid.
14
Q
A
15
Q
Boiling?
A
- Liquid - gas
- Boiling point is when the temperature at which a liquid changes to a gas throughout the liquid
16
Q
Evaporation?
A
- Liquid - gas
- The changes of a liquid to a gas at the surface of the liquid
17
Q
Condensation?
A
- gas - liquid
- The changes of a gas to a liquid
18
Q
Freezing?
A
- liquid - solid
- Freezing point where the temperature at which a liquid changes to a solid
