Question

Ice fishermen drill holes in ice covered lakes so they can fish in the cold winter months. The water beneath the layer of ice remains
liquid. If the ice sank to the bottom, the lake would freeze from the bottom to the surface. This would freeze all of the lake's organism.
Which property of water explains this occurrence?
A lower pH makes the water more acidic, resulting in the neutral ice floating
The bonds, between the water atoms, break expanding the ice molecules so that liquid water can fill the spaces in between the frozen water
molecules
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
The water's cohesive properties keeps the molecules close together, therefore, increasing the density ice.

Answer 1

Answer:

The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.

Explanation:

Water has awesome properties that distinguishes it among all other substances, many of which is attributed to its hydrogen bonding. Liquid water contains hydrogen bonds that holds tightly its molecules. However, when this liquid water freezes, the hydrogen bonds between its molecules break and expands. This creates space for the water molecules to occupy as it turns to its solid form (ice).

This is the case of this ice-covered lake. The ice, when it sinks, causes the liquid water beneath to freeze because the hydrogen bonds between the water molecules are being expanded enabling the molecules to occupy more space (volume) and make it less dense than liquid water (decreased density).
