water
water (H2O) Odourless, colourless liquid that covers about 70% of the Earth's surface and is the most widely used solvent. Essential to life, it makes up from 60–70% of the human body. It is a compound of hydrogen and oxygen, with the two H-O links of the molecule forming an angle of 105°. This asymmetry results in polar properties and a force of attraction (hydrogen bond) between opposite ends of neighbouring water molecules. These forces maintain the substance as a liquid, in spite of its low molecular weight, and account for its unusual property of having its maximum density at 4°C (39.2°F). Besides its everyday uses, water is used to manufacture sulphuric acid, nitric acid, sodium carbonate, and ammonia; it is also employed to extract oil and sulphur from the ground. Properties: r.d. 1.000; m.p. 0°C (32°F); b.p. 100°C (212°F).
