What would it be like to pour water into space!

Theoretically, it will float in space, but because the heat of the sun is high, the water will vaporize and disappear.

It turns into small round droplets.

Turn into water droplets and travel through space.

Space is vacuum, and water is simply gone.

Because of gravitation, the gravitational pull on water in space is very small.

Main information:

Space (English: space), which the Chinese dictionary explains is extremely high sky. The International Aviation Federation (IAF) in Geneva, Switzerland, defines the boundary between the atmosphere and space

The dividing line is 100 kilometers (about 62 miles) above sea level, which is called the Kármán line. The Kármán line is named after the American scientist Theodore von Kármán.

Geophysicists divide atmospheric space, or airspace, into 5 layers. troposphere, sea level to 10 km. The troposphere has dense air called a dense atmosphere. The air in the dense atmosphere becomes thinner and thinner as the altitude increases.

Stratosphere, between 10-40 km. mesosphere, 40 80 km. 80-370 km is the thermosphere, which belongs to the lower part of the ionosphere. The outer atmosphere, more than 370 kilometers of space, belongs to the upper part of the ionosphere.

From the Earth's surface to an altitude of 100 kilometers, there is less and less air as the altitude increases. About 75% of the atmosphere above the Earth is in the troposphere and 97% below the stratosphere. The density of air in the thermosphere is 1% of the Earth's surface, and air continues to exist at an altitude of 10,000 kilometers in outer space, and there are still air particles at an altitude of 100,000 kilometers.

Therefore, there is no clear boundary between airspace and outer space.

Water cannot flow in space because of gravity (gravitational force). In space, there is no or almost no gravity, so water can only gather into clumps under the action of intermolecular van der Waals forces and surface tension, and cannot flow. In space, the blood of astronauts can flow because the blood flow in the animal's body is not due to gravity or gravity, but to the pressure (blood pressure) caused by the heartbeat.

With or without gravity, blood pressure is present, so blood can flow. If the blood flow within the blood vessels also relies on gravity, then it is troublesome. When a person stands on the ground, the blood will flow down the limbs, and the head will be in a state of ischemia forever.

In addition to atmospheric pressure, there is no oxygen in space to support combustion, and even fire cannot be lit, and in an aerobic environment, because there is no pressure in space, the boiling point of water is very low, and it may not even reach 10.

If the universe is in a vacuum, water has no liquid phase, not even a solid phase, so there is no boiling point.

That is to say, if you throw a glass of water into space, then under the sunlight they will immediately boil and then turn into a pile of steam, even if there is no sunlight, the water may boil (the inside may turn into ice), and the final result will be a pile of steam, and then there is no pressure, the water will become water molecules, become gaseous, and if there is no special pressure cooker or something, it is impossible to boil water. Extended information: Boil waterCorrect way to boil waterWhen the water is about to boil (80-90 degrees Celsius), open the lid, wait for the water to boil for another 2-3 minutes, then turn off the heat.

If you can't always get the right time for the water to boil, open the lid as soon as the water is boiling and wait another 2-3 minutes.

The reason for this is that there are more and more organic pollutants in the water now, some of which are volatile and volatilize with the water vapor when heated.

Therefore, when the water is about to boil, open the lid of the kettle and boil it for another two or three minutes after the water is boiling to allow these substances to be volatilized to the maximum.

On the other hand, boiling water for too long will also cause the water to deteriorate and form harmful substances.

Therefore, healthy water that meets the needs of the human body should be fresh, and the boiling time should not be too long.

It can boil in space, but its temperature is very low, that is, the boiling point of water in space is very low. Because the boiling point corresponding to the liquid decreases with the decrease of saturated vapor pressure, the pressure in space is almost 0, and the saturated vapor pressure required is also very low, so that the temperature required for boiling is very low, that is, it can be boiled, but the temperature is very low.

There is no oxygen in space to support combustion, not even a fire can be lit, and in an aerobic environment, because there is no pressure in space, the boiling point of water is very low, and it may not even reach 10.

First of all, our spacecraft is located in the Earth's orbit, and the weightlessness occurs because the spacecraft is running at high speed in the Earth's orbit. The spacecraft is affected by the gravitational pull of the earth, and because the spacecraft is running in the annular orbit of the earth at high speed, the centripetal force generated can cancel out the gravitational force brought by the earth, so the spacecraft can float smoothly in space, and the people and materials in the spacecraft have the same effect. The water droplets are stationary relative to the spaceship, and at the same time, the spacecraft floats smoothly in the Earth's orbit in space at high speed.

Therefore, the water droplets in the spacecraft always remain weightless, and because of the intermolecular forces of the water droplets themselves, the water droplets can maintain a spherical state in the spacecraft. If the spacecraft returns to Earth, the droplets will turn into a small pool of water. Gravitational and intermolecular forces present us with so many amazing phenomena, as long as we understand the mysteries, many magical phenomena will be solved by us one by one.

Space microgravity environment is very interesting, our tears will not flow downward, but will be attached to the corners of our eyes like a bead, wet towel in microgravity environment is very difficult to dry, because the water will not be affected by gravity and has been attached to the surface of the towel, and after relaxing the towel back to the original wet towel state. Therefore, the circular shape of the water droplets in the spacecraft is caused by gravity and intermolecular forces.

All matter on Earth will be subjected to gravity, i.e., attracted to the Earth.

In space, because it is far enough away, the matter in space will not be affected by the earth's gravity, and it can fly with a little thrust. This is the case with water in space.

We know from many reports of life in space that astronauts float in space. So why is this happening?

Most people think that this is because there is no gravity in space, and this view is not true. In fact, this is because people are in a state of weightlessness when they "free fall" in space, and they cannot feel gravity and have the illusion of no gravity, which feels like floating in space. You can imagine the scene of people in the elevator, if the steel cable of the elevator is suddenly broken, then the elevator room and the person in the elevator fall down sharply at the same time, then the person is equivalent to no weight for the elevator, which is the state of weightlessness.

Therefore, people are not floating in space, they just don't feel the presence of gravity.

The Earth's water, of course, will float into space. It is important to know that there are three types of water on the earth: solid, liquid and gaseous, liquid and solid water are attached to the earth's surface, while gaseous water molecules can be dispersed out of the earth through thermal motion, but the total amount is very small.

Due to the orbit of the solar system in which the earth is located, a large amount of water exists in a liquid state, a small amount exists in a solid state, gravity makes water molecules gather together and attach to the surface of the earth, these two parts of water are basically impossible to float out of the earth, but there is also a part of the existence in a gaseous state, the spacing between gaseous water molecules is more than 100 times the diameter of the molecule, and the interaction between molecules is relatively weak (whether it is gravity or other forces are related to distance).

This part of the water molecules will move with the atmosphere, and the molecules of the substance are constantly moving in heat, so there is a diffusion phenomenon, and some molecules will move away from the air flow and drift away to the point where they don't know it. There are also very thin distribution of water molecules at the edge of the Earth's atmosphere, and their thermal motion may naturally detach them from the Earth.

There are about 10 trillion tons of water in the earth's atmosphere, which is much less than the amount of liquid water (13.6 billion billion tons), and the vast majority of the atmosphere is concentrated in the range of 100 kilometers from the ground, and the influence of gravity also makes the vast majority of water vapor concentrated in this range, and then the upper atmosphere is very thin, plus the earth's atmosphere is more than 1000 kilometers thick, and the direction of molecular thermal movement is not fixed, and many float out and back. This layer of the atmosphere, which gradually loses matter due to thermal motion, is called the dispersed layer, and because the air has very little gravitational pull, gases and particles can fly out of the Earth's field and into space.

The loss of water molecules on the earth is relatively small, and the earth can also capture some asteroids or meteorites with high water content from space, which is also replenishing the water on the earth, so the water on the earth has not disappeared much for billions of years, and it is still enough to maintain the liquid environment ecology of the earth.

Because the Earth has a strong gravitational pull that attracts objects closer to the Earth, water from the Earth will not be spilled into space.

Because the earth is attractive, and water has a certain attention, water will not be sprinkled into space, but on the ground.

In my opinion, this is because of the gravitational pull of the earth, which can hold water firmly on the surface of the earth. This prevents water from floating on Earth into outer space.

Since the water molecule is a polar molecule, there will be a static tension between the two water molecules, and with the gravitational force between the molecules, the water will inevitably accumulate into a standard sphere in a completely weightless state. If it is ideal, that is, there is no force (including the gravitational pull of other celestial bodies) or the net force of the force is 0, etc., the water droplets should be spherical. If the net force of the force is not 0, then it should be elliptical.

Exactly what is related to the accuracy of the stem, because the temperature in space is 3 Kelvin, infinitely close to absolute zero, so water exists in space in a solid form, so it is not possible to say exactly what shape it is. Complete.

The states of water in space are:

1. Liquid spheres, under weightless conditions, water will form spheres to achieve the equilibrium state of minimum surface area and intermolecular force balance.

2. Solid, the temperature of space is low, and the vast majority exist in the form of ice.

3. Gaseous state, the boiling point and pressure of space and the earth are different, and a small amount of liquid water will vaporize into a gaseous state.

The states of water in space are:

1. In the liquid sphere, under the condition of weightlessness, the water will form a sphere to know clearly, so as to achieve the minimum surface area and the equilibrium state of the intermolecular force in the state of flat sail spring balance.

2. Solid, the temperature of space is low, and the existence of ice forms accounts for the vast majority.

3. Gaseous state, the boiling point and pressure of space and the earth are different, and a small amount of liquid water will vaporize into a gaseous state.
