water
« on: December 20, 2011, 08:50:41 AM »
Water (H2O) is the most abundant compound on Earth's surface, covering about 70%. In nature, it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for all life on Earth.Water usually makes up 55% to 78% of the human body.

Water is an useful creation of life. It is very essential element in the earth. It is very useful for us. We can not lead a moment without water. But we polluted it randomly. We should prevent water pollution.

Many harmful  substances also dissolve in water though it is commonly referred to as the universal solvent. Because of this, we suffer many dieases due to drink impure water.So we should always try to drink pure water to keep our health sound.
