  1. 1. Interesting facts about water Andrew Peterson 6d
  2. 2. Table of Contents 1.Water as a chemical compound 2. The role of water 2.1The amount of water in several organisms 2.2Water as a cause of death 3.Water. Physical aspects 3.1 Physical form of water 3.2 When water is like glass 4. Chemical property of water
  3. 3. 1. Water as a chemical compound Water is the most simplest and common substance on the Earth. However, it holds a plenty of secrets. At present, scientists continue analyzing qualities of water. They find more and more interesting facts about it. Definition: Water is a chemical compound with the chemical formula H2O. A water molecule consist of one oxygen (O) and two hydrogen (H) atoms
  4. 4. 2.THE ROLE of WATER WATER is very important for the life of animals, plants, people. All living beings consist of WATER. 2.1 The amount of water in several organisms The following list shows the amount of water in different organisms: animals – 75% fish – 75% Jelly-fish –99% potatoes - 76% apples - 85%  tomatoes -90% cucumbers - 95% melon -96%. Human newborn child- 86% Elderly people - <50%
  5. 5. 2.2 Water as a cause of DEATH Water could SAVE or KILL. Be careful! 85% of all diseases in the world are transferred through water! Every year 25.000.000 people dies because of those diseases!!!
  6. 6. 3. WATER.PHYSICAL ASPECTS 3.1. Physical forms of water 1.Water appears in nature in 3 common states of matter -solid, liquid, and gas. However, scientists distinguish 5 different states of water in liquid and 14 states in solid form. 2. From hot water to ice. To get ice from HOT water, firstly, it should get cold. Why couldn’t we use already COLD water? Surprisingly, many experiments showed that hot water could turn into ice faster than cold water. 3. Water freezes under 0 C, boils at 100 C. However , VERY pure water could stay liquid with freezing temperature!!!
  7. 7. 3.2 When water is like a glass Under -120 C - water becomes sticky and thick Under -135 C - water becomes similar to GLASS( solid and without crystal structure).
  8. 8. 4. Chemical property of water Water could be DANGEROUS. For instance, in Azerbaijan, there is water which could go up in flames because of a great amount of methane in it.
