Everything is made of atoms. … A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.
What is water making?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. … In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2).
Is water naturally made?
How is water made in nature? Research suggests that the water on Earth came from asteroids and heavy clouds of gas and dust soon after the formation of the sun. Moreover, Earth’s atmosphere is filled with oxygen, which joins with deuterium and hydrogen to create water.
How is water made in space?
Water is abundant in space and is made up of hydrogen created in the Big Bang and oxygen released from dying stars.
Why is water called water?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).
Can we create water?
Theoretically, this is possible, but it would be an extremely dangerous process, too. To create water, oxygen and hydrogen atoms must be present. Mixing them together doesn’t help; you’re still left with just separate hydrogen and oxygen atoms. … The hydrogen and oxygen atoms’ electrons’ orbits have been conjoined.
Is the water alive?
Water is not a living thing, and its neither alive or dead.
Will the Earth run out of water?
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. … More than a billion people live without enough safe, clean water. Also, every drop of water that we use continues through the water cycle.
Who invented water?
Who discovered the water? It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).

How was water created?
The new research suggests that Earth’s water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun’s formation, called the solar nebula. … In the case of Earth’s oceans, the deuterium-to-hydrogen ratio is close to what is found in asteroids.
How do astronauts pee?
There are two parts: a hose with a funnel at the end for peeing and a small raised toilet seat for pooping. … To pee, they can sit or stand and then hold the funnel and hose tightly against their skin so that nothing leaks out. To poop, astronauts lift the toilet lid and sit on the seat — just like here on Earth.
What Colour is water?
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
Is water wet?
Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.
What is water for kids?
Water (H2O) is a transparent, tasteless, odorless, and almost colorless chemical substance and covers over 70% of Earth’s surface. … No known life can live without it. Lakes, oceans, seas, and rivers are made of water. Precipitation is water that falls from clouds in the sky.
What year will we run out of water?
Unless water use is drastically reduced, severe water shortage will affect the entire planet by 2040.
Can water be destroyed?
Water is neither created nor destroyed in nature. The amount of water on the Earth has remained constant in the previous two Billion years as it is continually replenished by the Water Cycle. Water does not escape the earth, so it being destroyed does not come in the equation.
Can water get expired?
Water doesn’t go bad. Having a freshness date on a bottle of water makes about as much sense as having an expiration date on sugar or salt. … Although water, in and of itself, does not go bad, the plastic bottle it is contained in does “expire,” and will eventually start leaching chemicals into the water.
Is the ocean alive?
The Ocean covers over 70 percent of our planet’s surface and accounts for 97-99 percent of the liveable biosphere. … The Ocean Is Alive is first and foremost a celebration of the Ocean in all her living splendour.
Does water have DNA?
River water, lake water, and seawater contain DNA belonging to organisms such as animals and plants. Ecologists have begun to actively analyze such DNA molecules, called environmental DNA, to assess the distribution of macro-organisms. … In a natural environment, these processes can operate in a complex way.
Is a rock alive?
Rocks do not reproduce, they do not die, and therefore they were never alive. … Life is the process of self-preservation for living beings and can be recognised by life processes; such as eating, metabolism, secretion, reproduction, growth, heredity etc.
Can you drink ocean water if boiled?
Boiling seawater does not make it safe to drink because it does not remove the salt. On Average, seawater holds 3.5% salt, too much for the body to process. As seawater boils, it evaporates, leaving the salt behind. You’re making the seawater saltier by boiling it.
How old is the water we drink?
The water you drink may be composed of the same water molecules that have been around since life started on this earth 4.6 billion years ago.
Can Earth run out oxygen?
Yes, sadly, the Earth will eventually run out of oxygen — but not for a long time. According to New Scientist, oxygen comprises about 21 percent of Earth’s atmosphere. That robust concentration allows for large and complex organisms to live and thrive on our planet.
Who invented walk?
A hominin whose anatomy was so like our own that we can say it walked as we do did not appear in Africa until 1.8 million years ago. Homo erectus was the first to have the long legs and shorter arms that would have made it possible to walk, run and move about Earth’s landscapes as we do today.
Why is water liquid?
At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second. Water molecules are constantly on the move.
Is there water in space?
Is there water in space? … And now, scientists have found an enormous cloud of water vapor floating in space. Located 30 billion miles away in a quasar – a massively powerful cosmic body – the water cloud is estimated to contain at least 140 trillion times the amount of water in all the seas and oceans here on Earth.
Can scientists make water?
Summary: Scientists have discovered a new way to make water. Not only can they make water from unlikely starting materials, such as alcohols, their work could also lead to better catalysts and less expensive fuel cells.
How old is the ocean?
The ocean formed billions of years ago.
At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
Can you fart in space?
The official verdict on gas in space: No burps, more farts, and no, you can’t use your flatulence to propel you around the shuttle.
How do female astronauts deal with periods?
A combined oral contraceptive, or the pill, used continuously (without taking a week off to induce menstrual flow) is currently the best and safest choice for astronauts who prefer not to menstruate during missions, says Varsha Jain, a gynecologist and visiting professor at King’s College London.
Do astronauts eat their own poop?
The scientists of the Penn University said that the new process includes mixing human excreta with microbes which will eventually turn it into edible substance.
Why is the ocean salty?
Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. … Ocean water seeps into cracks in the seafloor and is heated by magma from the Earth’s core. The heat causes a series of chemical reactions.
What does water smell like?
Hydrogen sulfide gas, which smells like rotten eggs, may occur naturally in well water. … Most frequently, however, the smell of sulfur in your water is likely due to the existence of sulfate-reducing bacteria, which produces hydrogen sulfide as a byproduct.
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
Can water be dried?
Dry water actually consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid. The result is a white powder that looks very similar to table salt. It is also more commonly known among researchers as empty water.
Is fire dry or wet?
Fire is a chemical reaction, so “dry” is meaningless when talking about it. Water is wet, but fire is not dry. When you burn organic material, like wood or wax, all the hydrogens are converted into water, H2O. If you burn glucose, fully half of the volume of the gases produced is water vapor.
Is the ocean wet?
If we define “wet” as a sensation that we get when a liquid comes in contact with us, then yes, water is wet to us. If we define “wet” as “made of liquid or moisture”, then water is definitely wet because it is made of liquid, and in this sense, all liquids are wet because they are all made of liquids.
