How does the ice float in the water?
Ice is less dense than water. Therefore, a mass of ice displaces a larger volume of water than it’s own mass. It is the same principle as making a steel ship float on the ocean. Ice is less dense than liquid water because, as it forms crystals, the water molecules line up in a more widely-spaced formation. This is due to hydrogen bonding. The temperature of maximum density for water is 4°C, but water crystallizes into ice at 0°C.
