What are the two consequences of anomalous expansion of water?
Some consequences of anomalous expansion of water are freezing the top layer of lakes and ponds, bursting of water pipes and damage to crops.
What are the effects of anomalous Behaviour of water?
Effects if Anomalous expansion of water: When the temperature of water on the surface falls below 40C, it expands and thus being lighter it does not sink down. Thus the temperature of water at the surface of water cools down to 00C or below forming ice, but under the ice there is dense water at 40.
What are the advantages of anomalous expansion of water?
With a further drop in temperature water on top forms ice and become a bad conductor of heat. This stops the heat from escaping the water body and helps the aquatic life to survive. Hence, aquatic life can survive even when the temperature reaches or falls below.
What is the anomalous expansion of water and explain its significance?
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4°C to 0°C, and it becomes less dense. The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.
What is meant by anomalous expansion of water describe its effects on every day life?
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. The density is maximum at 4 degree centigrade and decreases below that temperature as shown in graph.
What is meant by anomalous expansion of water how it is helpful for the survival of aquatic species?
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.
What is the importance of anomalous Behaviour of water by using Hope’s apparatus?
when a student want to make an experiment on water boiling point,when water its placed in a barrel and placed on fire,these anomalous particles of water vibrates evenly making convectional current movement of water thus enabling it to reach at the maximum boiling point.
What is the role of anomalous behaviour of water in preserving aquatic life?
The anomalous behaviour of water is that from 0°C to 4°C it contracts and beyond 4°C it expands. This ice acts as an insulator and does not allow the temperature of the water layer below it to fall below 4°C. This ensures that a liveable temperature is maintained for aquatic life under the oceans and rivers.
Why the anomalous expansion of water is maximum at 4 degree?
On cooling water, the rate at which the molecules are whizzing around decreases as they lose energy. On further cooling, the water molecules start squeezing together, increasing their density. At 4oC the density reaches its maximum and after this, the water molecules can squeeze no further.
What is the role of anomalous Behaviour of water in preserving aquatic life?
In what way is the anomalous behavior of water advantages to aquatic animals?
The anomalous expansion of water helpspreserve aquatic life during very cold weather. … If the temperature falls further, the top layer expands and remains on the top till it freezes and the ice layer acts as an insulator and HELPS the dishes and other aquatic animals to sustain .
