Water is a transparent and nearly colorless chemical susbstance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.
Strictly speaking, water refers to the liquid state of a substance that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.
Water is used for so many things asides drinking; cooking, baking, washing, bathing, as a solvent...so so many things. So how can we make use of this indispensable commodity and not understand the enormity and versatility of its potentials?? So then...
In continuation of super - amazing facts about water...I have it on good authority that...
* More chlorine enters the body through dermal absorption and inhalation while showering than through drinking tap water.
* Skin pores widen while showering, making dermal absorption of chlorine and other chemicals possible.
* Showering in filtered water results in greater respiratory health by reducing the risk of asthma and bronchitis from chlorine inhalation.
* In just one day, 200 million work hours are consumed by women collecting water for their families.
* 1/3 what the world spends on bottled water in one year could pay for projects providing water to everyone in need.
* A jellyfish and a cucumber are each 95% water.5
* Water expands by 9% when it freezes.8
* Each day, we also lose a little more than a cup of water (237 ml) when we exhale it.
* Chicken and goat are the least water intensive meats to consume.
* Hot water can freeze faster than cold water under some conditions (commonly known as the Mpemba effect).
* If the entire world’s water were fit into a 4 liter jug, the fresh water available for us would equal only about one tablespoon.
* Water regulates the Earth’s temperature.23
* Over 90% of the world’s supply of fresh water is located in Antarctica.23
* Two-thirds of the world’s population is projected to face water scarcity by 2025, according to the United Nations.
* Water from a sea or ocean is known as seawater. On average, every kilogram (2.2lb) of seawater contains around 35 grams (1.2 oz) of dissolved salt.
* 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 (28.4 °F).
* Water makes a good solvent with many sugar, salts and acids easily dissolving in it. On the other hand oils and fats don’t mix well with water.
* The water cycle involves water evaporating (turning into a gas), rising to the sky, cooling and condensing into tiny drops of water or ice crystals that we see as clouds, falling back to Earth as rain, snow or hail before evaporating again and continuing the cycle. Learn more about the water cycle.
* Water in the form of ice is found at the polar ice caps of the planet Mars, some scientists have also suggested the possibility of liquid water on the red planet.
* Pure water has no smell and no taste, it also has a pH level around 7.
* Drinking water is needed for humans to avoid dehydration, the amount you need each day depends on the temperature, how much activity you are involved in and other factors.
* An important use for water is in agricultural irrigation, this is when water is artificially added to soil in order to assist the growth of crops.
* Water is used frequently by firefighters to extinguish fires. Helicopters sometimes drop large amount of water on wildfires and bushfires to stop fires spreading and limit the damage they can cause.
* The water industry helps deliver water to homes in various cities and countries around the world. This can involve services such as purification, sewage treatment, filtering, distillation and plumbing.
* Electricity can be created from hydropower, a process that uses water to drive water turbines connected to generators. There are many hydroelectric power stations around the world.
* Water also plays a role in cooking. Steaming and boiling food are well known cooking methods. You may have noticed this last time you made pasta or noodles.
* Water is also used for fun. Water sports are a very popular recreational activity and include things like swimming, surfing and waterskiing. Ice and snow is also used in ice skating, ice hockey, skiing and snowboarding.
* Human bones are 25% water.
* Bottled water can be up to 1000 times more expensive than tap water and it may not be as safe.
* Water is sticky. The molecules love to stick to things, especially each other. It's what gives it such a large surface tension. It keeps you alive: it means water can pull blood up narrow vessels in the body, often against the force of gravity.
* The biggest known cloud of water vapour was discovered by Nasa scientists around a black hole 12 billion light years from Earth. There is 140 trillion times as much water in it as all the water in the world's oceans.
* All the water on Earth arrived in comets and asteroids. It happened between 4.5bn and 3.8bn years ago, a period called the Late Heavy Bombardment.
* The Antarctic has been covered in ice for more than 30m years. Right now, it is covered by 10 thousand trillion tons of snow and ice.
* It takes 100 litres to make 2 slices of bread and 65 litres to make the cheese filling in your sandwich.
So in drinking or using water...do them with wisdom...Thank you!!
