Question

What is the properties of the water shown in the picture

called ? how does it benefits aquatic animals ?​

Answer 1

Answer:

High specific heat

High specific heat refers to the amount of energy that is absorbed or lost by one gram of a specific substance to change the temperature by 1 degree celsius.

A relatively constant temperature without spikes and drops is essential to sustain life, as most organisms require temperatures to remain within a narrow range for their survival.

Answer 2

Answer:

The property of water shown in the picture is called "Anomalous Expansion of Water".

This property of water helps aquatic animals by preserving them during very cold weather. In cold weather when the temperature starts falling below 4°C in winter, the water at the surface of a pond or lake, water near the surface begins to lose heat energy to the atmosphere, becomes denser, and sinks, the warmer less dense water near the bottom rises. However, once the colder water on the top reaches temperature below 4°C it becomes less dense and remains at the surface where it freezes. When the temperature falls below 0°C, water at the surface gradually freezes into ice, but water well below the ice layer remains at 4°C. Since ice is a poor conductor of heat, ice now checks the flow of heat from the water of the pond (or lake) to the atmosphere. As a result, aquatic animals remain alive in the water of the pond (or lake), though the water of the surface has frozen into ice.

If water didn't have this property, lakes and ponds would freeze from the bottom up, which would destroy much of their animals and plant life.
