Anomalous Expansion of Water.
When water heated from 00C, the volume of it goes on decreasing and become minimum at 40C then only after as the temperature increases volume of water also increases.
|
Advantage of Anomalous expansion of water:- If pound surface water get freezed even though at bottom there may up to 40 and that temperature water living being may survive.
Disadvantage of Anomalous expansion of water:- Water pipe break at cold season. Bottle may break when it put so long time in freeze etc.
Q. At cold season surface water on pound may freeze but how water living being may survive ?
→ If pound surface water get freezed even though at bottom there may up to 40c and at that temperature water living being may survive.
Q. Completely full with water bottle may brust when it put in refrigerator?
→ Because of volume of water goes on increasing as the temperature of water decreases from 40c which may cause brust to bottle.
Q. In cold season water pipes may brust, why?
→ Because of water goes on increasing as the temperature of water decreases from 40c. This tends ot occupy more space which may cause brust to water pipes.
Q.Cock, Fanta or Beer is not completely full of bottle, there is always some vacant space, why ?
→ In Cock, Fanta or Beer also there is some water present. When it is kept in refrigerator temperature goes on decreasing and after 40c water volume increases which may cause brust to bottle, so not completly filled.
Do Yourself
- A glass is completly filled with liquid of fixed temperature. Either heating or cooling liquid in glass overfload. Which liquid is in glass and what is the temperature of it.
- When water is heated from 00 to 100 what difference occurs in volume and density of water?
- Water of 40C is completely filled in class. Now on heating or cooling, in both case water overflowed, give reason ?
