1. Matter Anything that has mass and takes up space
2. What are the solid, liquid, gas
three states of
matter?
3. properties of -The particles are packed closely together
solids -They have very little space to move so they can only vibrate
-The movement of particles is small and very slow
-Solids cannot be compressed
-solids keep their shape
4. The properties of - particles are loosely packed
liquids -The movement of particles is slow but faster than in solids
-can flow
- have no fixed shape, take the shape of a container
-take up a definite space
5. The properties of - particles are far apart
gases - can flow

- can be compressed
- have no definite shape
-take up all the space available
-Gas particles will escape from an open container
6. Examples of gas- -water vapour
es -oxygen we breathe in
-carbon dioxide we breathe out
-helium used in ballons
7. change of state When a material changes from a solid to a liquid, from a liquid to a gas, or from a
gas to a liquid.
8. Melting The change of state from a solid to a liquid; occurs when solids are heated.
Example: If you add butter to a frying pan it melts and becomes liquid.
