Water, the primary component of the Earth’s hydrosphere and the fluids of all known living organisms, is an inorganic, clear, tasteless, odourless, and virtually colourless chemical material. Even though it offers no calories or organic nutrients, it is essential for all known forms of life.
1. 97 % of water on our planet is salty. In the polar ice caps, 2.1% is locked up, and less than 1% is usable as fresh water.
2. Two types of water exist: salt water and fresh water. Salt water contains, you guessed right, massive amounts of salt, while fresh water has less than 1 percent dissolved salt concentration. It is possible to use only fresh water as drinking water.
3. The freezing point of water lowers as the amount of salt dissolved in at increases. With average levels of salt, seawater freezes at -2 °C.
4. Water, since it dissolves more substances than any other liquid, is considered the “universal solvent” This implies that it brings along valuable chemicals, minerals, and nutrients everywhere water goes, either through the earth or through our bodies.
5. In a single drop of ocean water, there can be a lot happening. Most certainly, millions (yes, millions!) of bacteria and viruses will have it. And they may have fish eggs, baby crabs, plankton, or even tiny worms as well.
