Particles in motion

Fixed volume Fixed shape Does not flow easily Cannot be compressed

Fixed volume Takes the shape of its container flows easily Can be slightly compressed

No definite volume No definite shape Particles spread out/use maximum space Can be compressed

Particles close together Arranged in a regular pattern Particles vibrate around a fixed point

Particles close together Particles arranged randomly Particles slide over each other randomly and slowly

Particles far apart Arranged randomly Move randomly and rapidly

The change in state from a gas to a liquid

The change in state from a liquid to a gas below the boiling point of the liquid

The change in sate directly from solid to gas or gas to solidwithout the liquid state being formed

The random movement of small visible particles in a suspension caused by the unequal random bombardment of molecules of liquid or gas on the visable particles

The spreading movement of one substance to another due to random motion of the particles

particles in solids, liquids and gases behave as hard spheres which are constantly mopving from place to place or vibrating
