Question

3)
is an example of anomalous behaviour of Water,
a) Dew point
b) solidification
c) cracking of rocks
d) evaporation​

Answer 1

Explanation:

Dew point is an example of anomalous behavior of water. This anomalous expansion of water is an abnormal and unique property of water which shows expansion of water instead of contracting when the temperature goes from 4°C to 0°C, and water becomes less dense.

Reason :

Reason :The water molecule, consisting of 2 atoms of hydrogen and one of oxygen forms a Mickey Mouse head-like structure such that the ears are the hydrogen atoms and the head is represented by the oxygen atom. The oxygen atom side of the molecule is slightly negative while the hydrogen atoms side has a slight positive charge. This makes the water molecules drawn towards each other forming hydrogen bonds. Upon freezing, the molecules set themselves in an arrangement that is very open in nature and contains more space than the water in the liquid state. Hence, water is said to expand on freezing and becomes less dense. On the other hand, it contracts on thawing, much unlike most other liquids.

I hope my answer is correct and keep it up!!!

Good morning have a nice day

Answer 2

Answer:

a) Dew PoinPoint

Because Dew point anomalous expansion of water is an abnormal and unique property of water which shows expansion of water instead of contracting when the temperature goes from 4°C to 0°C, and water becomes less dense
