How does the density of frozen water help organisms living within a lake in cold temperatures?

This property allows fish living in lakes and ponds to survive the winter. The ice that freezes on the surface insulates the water below so it stays warmer! In general, it is extremely unusual for the solid phase of a substance to be less dense than its liquid phase, but lucky for aquatic life it is!

Why can organisms survive when a lake freezes over?

When water boils at a certain temperature it turns into steam. Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds.

Why does water get less dense when it freezes?

This is due to ice’s density being less than liquid water’s density. Upon freezing, the density of ice decreases by about 9 percent. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

What would happen if water has its highest density at 0 C?

The density decreases as temperature increases. At temperatures near 0 °C, the water still contains many ice-like clusters. These clusters are free to move relative to each other, so water is still liquid. Thus, the density of water is a maximum at 4 °C.

What is not wet?

According to information obtained from a scholarly database,, “In a liquid-liquid interaction, such as water by itself, we can say that water is not wet, as molecules are all bound together and not wetting one another.” Though water has the ability to make other materials wet, the liquid itself is not wet.

Does oil make things wet?

No. Oil is not wet. Of course oil is a liquid, but ‘wet’ is used in surface chemistry with regard to interfacial tension of aqueous fluids. Similarly in a petroleum reservoir, oil will flow slowly past oil-wet rock, much faster past water-wet rock.

Is bottled water dead water?

Filtered and sterilized water is basically “dead” water, void of essential minerals and natural ingredients. There are no regulations to ensure safe drinking water from the viewpoint of what minerals important for our bodies are left in the water that we drink.
