Water
Good Morning Doctors …….. Good Morning My Friends ……
In the coming couple minutes, Gentle Men, I will talk to you about something we really need it because we can't live without it. Do you really want to know?
Listen carefully……
Water is very important in life. Water is the most common liquid on Earth. It covers 71% of Earth's area. Pure water has no smell, taste, or color. Lakes, oceans, and rivers are made of water. It is used in drinking, washing, ng, farming and industry. Plants and animals (including people) must drink water to live. It gives a medium for chemical reactions to take place, and is the main part of blood. It keeps the body temperature the same by sweating from the skin. Water helps blood carry nutrients from the stomach to all parts of the body to keep the body alive. Water also helps the blood carry oxygen from the lungs to the body. Water helps make urine. Urine helps remove bad chemicals from the body. The human body is 60–70% water.
The water in oceans is salt water, but lakes and rivers usually have unsalted water. There is only about 3% fresh water on earth, the rest is salt water. Water is a molecule made of 2 hydrogen atoms and 1 oxygen atom. Its formula is H2O. Water has a surface tension. So a little water forms drops on a surface, rather than spreading out to wet the surface.
Finally, we must take care of water and not waste or pollute it because it is a gift from Allah.
