Because there is no bottom and top in space, what happens to hot and cold air?

What happens to your birthday card in the room?Just look.

But now to your question.

You probably mean what happens to hot and cold air in a state of weightlessness, for example, in a space station.

In weightlessness you do not experience “under” and “above”, and there is no “lighter” and “heavier”, at most more or less mass.

In the same pressure, hot air has a lower density than cold air.On Earth, where we are “above” and “under” experienced, and “lighter” and “heavier”, it rises up.

About the condition in a space station is my answer is as follows.

In the space station, a quantity of hot air will simply linger where it hangs.It will slowly cool down because of its warmth to the environment in three ways:

1.By gradual mixing with the surrounding cold air: diffusion.

2.By the secretion of the kinetic energy of the molecules to the surrounding molecules of the cold air: conduction.

3.By issuing heat radiation to the environment: radiation.

What is lacking is the fourth factor, which depends on gravity: convection, rise upward with airflow as a result.

A candle in a space station will also struggle to keep on burning because no flame can form. The flame is the column of rising hot air that ensures fresh, oxygenated air supply.

Happy Birthday in space desired!

Besides that there is no top and bottom in space, there is still something, vacuum.Vacuum is not only the lack of particles ansich, but also the lack of gravity.

As you know, gravity is the effect that a larger object has on a smaller object by 芒 鈧?虄central Mass 芒 鈧劉.Above and below are concepts that people have devised, who live on a sphere in space, where they did not know that it was a. A sphere and B. Needed a conceptualization for above and below (direction the bearing area and direction where everything comes from fallen). Everything falls 芒 鈧?虄to芒 鈧劉 a larger object. That is attraction. The greater the mass and density of an object, the more influence it has on the smaller particles around it.

Now, back to the question.In space is not hot and cold. There is a very different spectrum of waves and forces at work. What we experience as warm, is the result of friction of atoms in motion. This is not true In space. Air is not there in space, so 芒 鈧?虄hot Air 芒 鈧劉 not at all.

What is equal everywhere is that 芒 鈧?虄radiating 芒 鈧劉 waves divide themselves over the present 芒 鈧?虄space 芒 鈧劉 and matter.In addition, the difference between that which has radiation (heat) and that which has not, lifted.

With above and below that has nothing to do with it.If there were air in the vacuum, these molecules and atoms would be balls together and form a uniform (Zegge a sphere) object. The temperature (radiation/movement of atoms), however, will disappear in the environment and will form 芒 鈧?虄freezing 芒 鈧劉.

According to the 2nd Law of thermodynamics, a lot of energy goes to little energy.M. A. W hot air goes to cold air until maximum entropy is reached. Only condition is that this can take place in a closed system. Above or below does not make anything out.

What matters above and below is the following:

On Earth warm air always goes upwards, because warm air has a lower density than cold air.So when your air heats turn air off, and you have fewer molecules per volume (lower density). This is also the reason why a hot air balloon flies upwards, until the hot air balloon enters an environment in which the air is so thin that the density is equal to the hot air balloon.
