Why is water such a special compound?

Answer 1

It's all about hydrogen bonding, which in this case occurs between the hydrogen and oxygen atoms of different water molecules. There are alot of ways it's unique sooo... (Heat capacity)This type of weak bonding allows water to hold substantial amounts of energy by the constant breaking of these hydrogen bonds; which thus requires even more energy to boil the water and makes it heat up slower. (Surface tension) Agian because of H bonding it causes the water on the top surface to be attracted to water below it creating higher tension because the forces ontop of the water is only downward while the forces are in every direction for water in the middle. (I think this counts for the sides also which causes capillary action in which plants use to carry water up from the roots) And this tension allows small things with greater density than water to float upon it (like bugs). (Universal solvant) Water interacts with substances that are being dissolved in it by circling the molecule and pulling on it with the slightly positive or negative sides of the water molecule thus splitting watever molecule into pieces. This is also called sphere of hydration. (Floating Ice) The hydrogen bonds form lattice structures between the water molecules at colder temperatures which causes it to take up more room than water which in part makes it less dense allowing it to float on water as ice. (Water is densest at 4*C) And ice floating is important because if it all sank to the bottom of the ocean, it'd never melt from the sun's rays and would eventually build up until the entire body of water was ice... and well we'd be dead at that point because we need the oceans to regulate our worlds temperature (part of the heat capacity part) I might be forgetting some stuff but oh wells ;D

Answer 2

1. Ice is slow to melt and water is slow to boil. Temperatures change slowly when changing form (phases) from liquid to solid to gas.
2. Under normal climatic conditions on earth, water exists simultaneously in all three phases. Can you name any other substance for which this is true?
3. Water is almost a "universal solvent". It carries nutrients and washes out hands and clothes. It is an inert solvent in that it does not react chemically to form new substances with the materials dissolved in the solution.
4. The density of water increases when it is cooled until about 4-degrees C. and then it expands. The water lines break when freezing occurs.
5. When we sweat, it cools our bodies.
6. The surface tension is very high which allows a bead of water to form a "roundish" drip from the faucet and allows to water to cling to soil particles.
7. Moist air is lighter (less dense) than dry air of the same temperature and has a tendency to rise.

Answer 3

There are several reasons water is special. One is because it's a great solvent. Another is because it has high cohesion. And a third is because it resists temperature changes.
