Water is most dense and thus heaviest at 4?C. At 0?C, ice forms and the ice can float on liquid water. Suppose ice were more dense than water at 0?C. What would happen in a lake at this temperature?
A. The ice would cover the bottom of the aquatic system and would build up in layers over time.
B. Ice would not form because solids are always less dense than liquids.
C. The ice would cover the surface of the aquatic system and would never melt.
D. 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.
A. The ice would cover the bottom of the aquatic system and would build up in layers over time.
