|
Water is a versatile solvent, and the temperature is regulated by substances dissolved in the fresh water.
|
|
|
Water forms hydrogen bonds with other water molecules at the surface of the water.
|
|
|
Water freezes and decreases the temperature of the water in the lake.
|
|
|
Water has the ability to moderate temperature.

Detailed explanation-1: -One of the unique properties of water is that it becomes less dense as its temperature decreases from 4° C until it freezes at 0° C. This allows many aquatic life forms to survive through the winter. If ice were more dense than water, it would freeze and sink over and over until the entire lake was frozen.
Detailed explanation-2: -The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts, becomes denser and sinks to the bottom. A circulation is thus set up until the entire water in the pond reaches its maximum density at 4°C.
Detailed explanation-3: -Answer and Explanation: One of the unique characteristics of water is that when it freezes, it actually becomes less dense.
Detailed explanation-4: -Water is less dense as a solid than as a liquid. This property is important, as it keeps ponds, lakes, and oceans from freezing solid and allows life to continue to thrive under the icy surface.
