What occupies the spaces between particles in a gas?

As you can see from the title, I'm puzzled as to what occupies the spaces in between the particles in a gas.

Take air for example. In Chemistry, I have learned that the particles in a gas are far apart. Hence the particles in the air around me are far apart. But if there are no particles in the spaces,it means no matter exists. So is it a vacuum? If so, why don't I experience it on a daily basis?

Sorry if the question is trivial, but it has been bugging me for some time.

Yes, it is vacuum. You don't "see" it as you much larger than the air molecules.

Note that the space between atoms, regardless of the state of matter, or even inside atoms, is mostly vacuum as well.

So in other words the distances are insignificant when compared to our size?

You can put it that way.

I can provide an explanation for what occupies the spaces between particles in a gas. The spaces between particles in a gas are not empty, but rather filled with a mixture of gas molecules and other particles such as atoms, ions, and free electrons. This mixture is known as the gas phase.

In the case of air, the spaces between gas particles are filled with a mixture of nitrogen, oxygen, carbon dioxide, and other gases. These particles are constantly moving and colliding with each other, creating pressure and giving the illusion of a continuous substance. This is why we do not experience a vacuum on a daily basis.

Furthermore, the concept of a vacuum is relative. In outer space, where there is very little matter, the spaces between particles are considered a vacuum. But on Earth, where there is a significant amount of gas molecules present, the spaces between particles are not considered a vacuum.

I hope this explanation helps to clear up your confusion and demonstrates the complexity of the gas phase. It is important to remember that even though the particles in a gas may be far apart, they are still present and interacting with each other.
