what is the anomaly of water?

Question

i need it asap!

Answer 1

There are at least two, possibly more, so not sure which you mean.

The first is that water expands when it freezes, with the result that ice is less dense than water and consequently floats on top.

The second is that water is a polar molecule, meaning roughly that it has a positively charged end and a negatively charged end, with the result that many different compounds (salt, for example) dissolve in it.

Answer 2

"The" anomaly?
1. When liquid water becomes solid, it expands in volume because of the crystal structure. (Most substances contract in volume when they go from liquid to solid.)
2. It has a high melting point, and a high boiling point, compared to other substances.
Well there are a lot of anomalies, see this website:

Answer 3

Here are a few anomalies:
Water phase anomalies 5
Water has unusually high melting point. [Explanation]
Water has unusually high boiling point. [Explanation]
Water has unusually high critical point. [Explanation]
Solid water exists in a wider variety of stable (and metastable) crystal and amorphous structures than other materials. [Explanation]
The thermal conductivity of ice reduces with increasing pressure. [Explanation]
The structure of liquid water changes at high pressure. [Explanation]
Supercooled water has two phases and a second critical point at about -91°C. [Explanation]
Liquid water is easily supercooled but glassified with difficulty. [Explanation]
Liquid water exists at very low temperatures and freezes on heating. [Explanation]
Liquid water may be easily superheated. [Explanation]
Hot water may freeze faster than cold water; the Mpemba effect. [Explanation]
Warm water vibrates longer than cold water. [Explanation]

Answer 4

it first starts to shrink when it gets colder.... like everything else, then start to expand again when it reaches freezing temps.

Answer 5

Wow, Thanks! I was asking myself the same question the other day
