Water is most dense and thus heaviest at 4°C. At 0°C, ice forms and can float on liquid water. Suppose ice were most dense at 0°C. What would happen in a lake at this temperature?
A. Ice would not form because solids are always less dense than liquids. B. The ice would cover the bottom of the aquatic system and would build up in layers over time. C. The cold temperatures and the subsequent ice formation would prevent hydrogen bonds from forming between the water molecules, thus causing the existing ice crystals to become disassociated from each other. D. The ice would cover the surface of the aquatic system and would never melt.
