Ten fun facts about water

Waterblogged.info–your future go-to site for up-to-date water-related information,–proudly kicks off its inaugural post with ten fascinating facts about water, shamelessly lifted from Wikipedia:

1. It really is blue. No, really.

2. It’s the only common, pure substance found naturally in all three states of matter.

3. It’s one of only a few substances that is less dense in its solid state, ice, than its liquid state. This is a good thing, if not completely understood.

4. In 1742, Anders Celsius defined the Celsius temperature scale with the freezing point of water at 100 degrees and the boiling point at standard atmospheric pressure at 0 degrees. The scale was reversed in 1745 by Carolus Linnaeus after Celsius’s death. It is not known whether Linnaeus said “duh.”

5. In some specific circumstances, hotter water freezes faster than colder water. This is called the Mpemba effect.

6. Hydrogen oxide and dihydrogen monoxide (DHMO) are two scientific names for water. The ominous sound of the second name, particularly its acronym, was the genesis of a hoax that led some innocents to call for the the banning of water, because, among other threats, it causes erosion and drowning and is a chief component of acid rain.

7. Water can react as an acid or an alkali, and also has an acid name, hydroxic acid, and an alkaline name, hydrogen hydroxide. Don’t memorize them; neither are widely used.

8. This may come as a shock, but pure water has a low electrical conductivity. Naturally occurring water always has impurities; even in tiny amounts these salts enhance water’s conductivity.

9. Ice is a general term for the 14 known solid states of water. Why ice is slippery is still a matter of scientific controversy.

10. Ninety-seven percent of the earth’s surface water is contained in the immense bowls of saline soup we call oceans. (Water, water, everywhere and all that.)
