Solids have a shape and a volume as the particles as only .

Drugi mogući odgovor:
fixed
vibrate

Liquids have a volume but they do not have a shape as the particles are able to .

The liquid will take the shape of the of the container.

Drugi mogući odgovor:
base
move

Pitanje 4
4.

The particles in a liquid can move past each other so the liquid can .

The particles in a solid can not flow so the solid does not take the shape of the of the container.

Drugi mogući odgovor:
flow.

During expansion the particles expand.

During expansion the substance get bigger.

During expansion the particles vibrate more and they occupy more space so the spaces between the particles get bigger.
