states of matter

SOLIDS? (four points) (PAN M)

- arranged in a fixed position

- very close together

- stay fixed to their neighbour

- can only vibrate

LIQUIDS? (four points) (PAN M)

- randomly arranged

- are close together

- always change neighbour

- can move around freely

GASES? (three points) (PAN M)

- randomly arranged

- lots of space between each other

- always change neighbour

- move around freely and very quickly

how does freezing/condensing work? (both work the same way)

cooling -> decreased energy -> particles move less -> particles stop moving around and just vibrate, forming a fixed shape attraction between particles form

how does melting/boiling work? (both work the same way)

heated -> increased energy -> particles vibrate more -> individual particles start to break free of the structure, forces are overcome
