Thousands have lived without love, not one without water
by W.H. Auden.
The quote says everything, it shows the entire essence of the value of this precious liquid that seems like a pretty simple substance- which is found everywhere in the world’s streams, lakes, oceans, and rain.
Without water, we can’t survive. It has become the synonym of life. Besides being the most important factor in life, it has many other things worth knowing.
Let’s explore some interesting facts about this universal solvent:
Water is sticky. The molecules love to stick to things, especially each other. It is what gives it such a large surface tension. It has the capacity to pull blood up the narrow vessels in the body, often against the force of gravity.
If we fit the entire world’s water into a 4-litre jug, the freshwater available for us would be only about one tablespoon.
The biggest known cloud of vapour was discovered by Nasa scientists around a black hole 12 billion light-years from Earth. There are 140 trillion times as much water in it as all of it in the world’s oceans.
We all know that the human body constitutes about 70% of water. But did you know that this keeps changing at different times of your life? A human fetus constitutes around 95%for the first months, getting to 77% at birth and 60-70% in adults. There are about 42 litres for a 70kg person.
There is ice on the poles of the moon, and on the poles of Mars and Mercury. Water water everywhere!
You use approximately 8 litres to flush a toilet – about the same as you use to brush your teeth.
Scientists have found a really big pool of water, actually a vapour just floating out there in the space. And when we say big, it means 100,000 times larger than the sun big! It has h2o equivalent to 140 trillion times the earth’s ocean.
It takes around 100 liters of water to make 2 slices of bread and 65 liters to make the cheese filling in your sandwich.
It has been found that there is a warm ocean under the icy crust of Enceladus- Saturn’s moon.
Children in the first 6 months of life consume seven times as much h2o per pound as the average American adult.
