Water is a fluid. Water is the only chemical substance on Earth that exists naturally in three states. There are over 40 anomalies (strange things) about water. Unlike most other liquids such as alcohol or oil, when water freezes, it expands by about 9%.This expansion can cause pipes to break if the water inside them freezes. Water is a molecule ma...
Plants and animals (including people) are mostly water inside, and 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. Wate...
The dihydrogen monoxide parodyinvolves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO) and listing some of its harmful effects in an alarming way. Some examples include talking about how "it causes burning, suffocation and corrosion," when it is actually just talking about hot water, drowning and rust. Sometimes the parod...
The weirdness of water
A BBC short item explains that every molecule on Earth has existed for billions of years, and all of them came from elsewhere. Water is alien because it arrived on asteroids and comets. It is the second most common molecule in the universe. Why is it not a gas? It is made of two very light elements. Ice floating on water is also an oddity, caused by the nature of water to expand and drop in density when it freezes. Also, hot water can freeze faster than cold, and both this effect and it's cau...
Water in the universe
Much of the universe's water is produced as a by-product of star formation.On 22 July 2011, a report described the discovery of a gigantic cloud of water vapor containing "140 trillion times more water than the Earth's oceans combined" around a quasar12 billion light years from Earth. According to the researchers, the "discovery shows that water has been prevalent in the universe for nearly its entire existence". Water has been detected in interstellar clouds in our galaxy, the Milky Way. Wat...
Origin of water on Earth: possibilities
We do not know exactly how the Earth came to have so much water. It is everywhere in the Universe, but it is uncommon for a place to have so much. The reasoning is like this: every element (except hydrogen and some helium) has been formed in stars. Therefore, oxygen was originally formed in stars. The formation of water is not a problem: it is exothermic, so forming the molecule from its atoms does not need outside energy. But to explain why the Earth has so much compared to, for example, Mar...

The square meter is the SI-derived unit of area. It has a symbol m² (33A1 in Unicode [1] ). It is defined as the area of a square whose sides measure exactly one meter. The square meter is derived from the SI base unit of the meter, which in turn is defined as the length of the path travelled by light in absolute vacuum during a time interval ...
