Which property of water is shown in the following picture? How is beneficial to aquatic animals in cold countries?
Answers
Answer:
For a start, water is a liquid. If water would freeze, then the fish would die. Water can disolve salt which lowers the freezing temperature by a few degrees Celcius. The amount of heat you need to remove for water to freeze is proportional to its volume. The volume of water in the oceans is gigantic. There are always currents, and internal energy sources from the Earth and the Earth/Moon gravity system to keep the oceans warm enough.
Answer:
Anomalous expansion of water
Explanation:
Water has minimum volume and maximum density at 4 degree C. As a lake cools towards 4 degree C, water near the surface becomes denser and sinks. Then the warmer, less dense water near the bottom rises. when this layer cools below 4 degree c, it freezes and being less dense, remains on the surface. Thus water bodies freeze at the top first and water at the bottom protects aquatic animals and plants.
