H2O, A simple atomic structure containing 2 molecules of Hydrogen and One molecule of Oxygen is what constitutes Water. Colorless and Odourless, Water is one thing that people use day in and day out. Some like Relaxing in a pool of water, while some prefer it in the ponds to fish. While most like it as a refreshing drink. Water is considered one of the most important needs for life, So much important that studies have proved that no organism can be born without the presence of water. No wonder, Scientists at NASA are spending billions of dollars to search for water on other planets.
78% of earth is water, two thirds of our body is water. In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state,water vapor or steam.
Water never sticks to anything other than itself.
As a simple experiment try opening a tap over the umbrella, Droplets of water join together and just drain off over the surface. This time, Try rubbing the surface with the water flowing. The water starts to seep through because this time we are trying disintegrate the droplets not allowing them to stick together and flow off.
Water has a boiling point of 100 Deg centigrade(212 deg Fahrenheit) and a freezing point of 0 deg centigrade(112 deg Fahrenheit), However the boiling point of water also depends on pressure, i.e. The water on the Mount Everest will start to boil at a lower temperature (68 deg centigrade) while the water on the bottom of the sea at a lot higher temperature than the regular 100 deg. So if u have to boil the water real fast, because mom says so; Mount Everest is a place where u want to be.
The tendency of water to move up hollow tubes against the force of gravity is called capillary action and the force called as capillary force. The Property is relied upon by plants to let water flow up towards leaves and branches. Being transparent it allows sunlight through it to allow plant photosynthesis to take place.
Biologically all the major components like fat, protein DNA are dissolved in water. Water soothes the body and keeps the body temperatures down. Water is also used a as a cooking agent that helps cook food faster, I cannot imagine cooking rice with without water. Even plants require water for their own life.
Water also helps keep the earth temperature down, The solid form of water, ice, helps keep things cool.
Water is a very strong solvent, that dissolves even acids. But some fats and oils that do not mix well with water are not soluble. The saturation point (The amount of salt that can be dissolved in 1 millilitre of the solvent) is pretty high making water the most preferred solvent. To create a ‘Dead sea‘ experience, one may have to dissolve over 6 tonnes of salt in a small 200 litre pool. The water however does not reach saturation. By dead sea experience i mean that people can float on the water without any life jackets, the biggest reason being the high salt content.
So much is water important for life, that organisms cannot be created in the absence of it. Ever wondered why dry food product have a longer use by date than the water based products? I guess u have the answer now, its the water content. Dry food products have no or low water content not allowing any bacteria or fungi to grow allowing them to be preserved for a longer time.
I remember throwing stones in stagnant water, see it bounce of the surface. What is the reason to it, it would sink normally. Talking about sink, Why do ships float while a screw made out of the same metal, sink?? And what would happen if u take a dive flat chested on water?
