Very Intresting News about WATER(H2o)

Water boils quicker when on top of a mountain than at the beach.
AT the beach- water boils at 212 degrees F. But on top of a mountain, say 5,000 feet- water boils at 202 degrees F. As the altitude gets higher, the air pressure becomes less. Since there is less pressure pushing on a pot of water at a higher altitude, it is easier for the water molecules to break their bonds and attraction to each other, thus it boils more easily.

Raindrops are actually shape like a hamburger bun.

DROPS of water coming out of a faucet are shaped like tear drops as we see them by the naked eye. The reason is the back end of the water drop sticks to the water which is still in the faucet until it can't hold on anymore. But- using high-speed camera- scientists have found that falling raindrops look more like a small hamburger bun. As the rain falls- the air below the drop pushes up from the bottom, causing the drop to flatten.Seawater is slightly more acidic than most natural fresh water.

NEUTRAL water such as distilled water has a pH of 7 which is in the middle point of being acidic and alkaline. Seawater happens to be slightly alkaline with a pH of about 8. Most natural water has a pH of between 6 - 8, although acid rain can have a pH as low as 4.

It takes about 7 times as much energy to turn boiling water into steam as it does to heat water at room temperature to the boiling point.

Distilled water is more pure than rainwater. Rainwater contains small amount of dissolved minerals that have been blown into the air by the winds. It contains tiny particles of dust and dissolved gases such as carbon dioxide and sulfur dioxide. Rain is produced by water vapor evaporating from the earth and condensing in the sky while distilled water comes from water vapor condensing in a closed container such as glass jar.

More things can be dissolved in water than sulfuric acid.

WATER can dissolve more substances than any other liquid. This is beneficial for mankind. Imagine what will happen if water will not dissolve the sugar at the bottom of your soft drinks and coffee. The water we see in the river, lakes, seas and oceans may look clear but it actually contains many dissolved minerals and elements. And because these things are dissolved- they can easily moved with water to all surfaces of the earth.

Condensation is water coming out of the air.

WATER that forms outside of a cold glass is liquid water condensing from water vapor in the air. Air contains water vapor. In cold air- water vapor condenses faster than it evaporates. So- when the warm air touches the outside of your cold glass- the air next to the glass gets chilled and some of the water in that air turns from water vapor to tiny liquid water droplets. Clouds in the sky on a cold day are condensed water-vapor particles.

Water has a high surface tension.

AMONG common liquids- water has the highest water tension. Mercury is higher. Surface tension is the ability of a substance to stick to itself- cohere. That's why water forms drops. Plants are happy that water has a high surface tension because they use capillary action to draw water from the ground up through their roots and stems.

Water expands when it frees

ACTUALLY, water expands when it freezes. This is unusual for liquids. Consider ice- it is one of the few things that floats as a solid. If it didn't then lakes would freeze from the bottom up and some lakes would be permanent blocks of ice.
