Explanation:

Effects if Anomalous expansion 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.

Answer 2

Explanation:  During winter in cold countries, the temperature falls below 0  degree celcius.

Water in lakes, seas or rivers will be frozen. Let us see how this happens.

The water at the surface, in contact with the cold atmosphere, loses heat and its temperature decreases. It becomes denser, sinks and is replaced by less dense water from the bottom. This process repeats itself so that the overall temperature of the water decreases.

Had water been like any other liquid, the whole depth of the water would have been frozen and aquatic life would have been destroyed completely.

Thanks to the anomalous expansion of water, when the temperature reaches 4 degree celcius.

 the water remains at the surface of the lake,sea or river. This is because as temperature decreases from 4  degree celcius to 0 degree celcius

water expands. The water is still less dense and thus remains at the surface. Only a small layer of water at the surface thus becomes frozen. Ice itself is less dense than water.

Answer: 1. Anomalous expansion of water is a blessing to marine life. In cold areas like those situated near the poles of the earth the temperature of water in ponds, lakes and oceans starts falling and goes down to 40C in the first phase in winter season. 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. This helps in serving the precious life aquatic animals.

 

2.In winter season the water supply pipes open to the atmosphere ofter burst when the temperature of the surrounding falls below 40C. This is due to the fact that water below 40 expands (anomalous expansion) and exerts pressure to the walls of the pipes and thus causes damage to it.

3.In rainy season a lot of water sweeps through numerous cracks and fissures in rocks. In water season when temperature falls below 40 going down to 00C or below, expansion of water take place, thus developing a high pressure. This results in the breaking of the rocks.
