ans:1)Solids are not easily compressed because their molecules are in a crystallized matrix that makes
the bonds very strongGases are spread out and the molecular bonds between gases are extremely weak
(the reason they have a tendency to explode ... because they're already floating around like bees). They
can be compressed easily because they are not actually 'connected' to each other

ans:3)it depends since water can change back to its hydrogen and oxygen gas forms when electric
currents are applied.

ans:4)Heat is being added to ice as it melts, but that heat is going into turning the water from a solid into a
liquid (breaking intermolecular bonds), rather than increasing the temperature.
