Refer to this diagram, gases particles move around a lot, intermolecular bonds are weak, in liquids particles move around a little intermoleular bonds are slightly stronger relative to gas phase, solid intermolecular bonds are stronger than liquid bonds molecules move around less than gas or liquid
