WATER

Water is an enigma. It is both simple and complex. Each molecule comprises just 3 atoms-2 Hydrogen and one oxygen. Yet scientist still do not fully understand how water molecules work. What we all know, though, is that water is essential to life, making up 80% by weight of all living things. Consider just five attributes of this amazing substance. 1. Water can store a lot of heat without a substantial rise in temperature, thus helping to moderate climate. 2. Water expands when it freezes, causing ice to float and form an insulating layer. 3. Water is highly transparent, enabling light-dependent organism to survive to considerable. 4. Water molecules produce surface tension, creating an elastic "skin". This tension enables insects to scamper about on a pond, causes water to form into droplets, and contributes to the capillary effect, which helps water to hydrate the talles plants. 5. Water is the most efficient solvent known. It is able to carry in solution oxygen, carbon dioxide, salt minerals, and many other vital substances. Water is a universal solvent.
