What is Water,Importance of water and Properties of water?

 Today I discuss the topic of water deeply and briefly.

 What is Water, the Importance of water and Properties of water?

• What is water?

Water is a substance that is made up of oxygen and two hydrogen elements, that exist in liquid, solid and gaseous states. It is a very necessary and useable compound. The water chemical formula is H₂O. It is an odourless, tasteless, inorganic and transparent thing. It is colourless in some quantity but it shows bluish colour when the light of red wavelength like the sun passing through it. Water is an excellent solvent. It is the main constituent and element in the Earth's hydrosphere.

• Importance of water:

Water plays important role in the development of any country. It is the important thing on Earth. It is the God gifted thing on the Earth for humans and animals. without water, life is impossible on Earth. Even that the human body contains 60% of water. The brain and heart of human-made up 73% of water and the lungs are composed of 84%. The skin of the human body is made up of 64% water and the kidney is made up of 83% water even that the bones are also made up of 31% water. On the Earth 71 % of water. The 3/4 part of our earth contains water. That is mostly in the seas and the oceans. A small part contains in the groundwater. water also exists in the form of glaciers and in icecaps in Antarctica.

• Properties of water:

Water is a universal solvent because it has the ability to dissolve many things. It is a polar and inorganic compound that is tasteless and odourless. Water plays a very important role on the earth. It is the main constituent of the earth. It is a transparent thing. The freezing point of water is zero Celsius and the boiling point is 100 celsius. The density of water is 1000kgm^-3.The melting and boiling point of water depending on the pressure.

• ^{Water Cycle:}   

When sun rays pass on the surface of the water in the ocean then due to sunlight water converts into water vapours then it converts into clouds in the sky. Clouds are the suspended water. Then clouds move into the earth surface and then they precipitate on the surface of the earth as rain, snow, fog. Water continually moves through the water cycle of evaporation, condensation, precipitation, evapotranspiration, runoff and move into the sea. It is a water transfer cycle.

• Role of water in Economy of World:

In the economy of the world, water plays an important role. Approximately 70% of the water that's is used in the Agriculture sector by human beings. Long-distance trade of different things like oil, gas and other commodities that are transported by boats, ships etc. Water is an excellent solvent for washing. Water, ice, snow plays an important role in different sports in the world. Fishing and other aquatic animals that is the great and large source of food that plays important role in the economy of the world.

• Quran says about water:

God says about water in QURAN PAK: "We made from water every living thing".In QURAN PAK SURAH 21 God addresses with people we made every living thing from the water. Water is a precious thing from God. God says: "The rain that Allah sends from the Heaven gives life to the Earth after its death." God declared that water is the basic and origin of life. Water is the basic and absolute thing on the Earth because without which survival of life is impossible. Allah said: "We send down pure water from the sky."

• History of Water:

Two hundred years ago, ARISTOTLE considered that water is one of the fundamental components that included in fire, air and earth. The scientific name of water is H₂O. It contains one oxygen atom and two hydrogen atoms that move very fast when heat and then it breaks down and escape in the air as vapour and steam.
At last, I want to say something:
              " WATER SAVES LIFE, NO WATER NO LIFE. WATER IS THE SOURCE OF EXISTENCE AND SURVIVAL ON THE EARTH. WATER IS THE ORIGIN OF LIFE ON THE EARTH."
