water contracts when cooling until about 4 deg. C. From that temp. further cooling causes the water to expand. as it freezes it continues to expand, that is why ice floats.
Why does ice still melt in water?
Fire is pure energy being released. And it takes energy to move molecules around. Where ice is concerned, the water molecule has been sapped of all energy which causes it to remain in place and stick to other water molecules.. When the energy from fire comes in contact with the water molecule, the molecule absorbs the energy which causes the molecules to break away from each other and move. When the molecules break away and move is what causes a solid like ice to become a liquid.
