Exploring the Space Between Atoms/Molecules in Gases

In summary, the conversation discusses the concept of vacuum and empty space in relation to gas atoms. While the dictionary definition of vacuum is a space devoid of matter, the discussion brings up the question of whether gas atoms can be considered a vacuum. The idea of light and virtual particles also complicates the definition of vacuum in modern physics. Ultimately, it is agreed that, from a classical and colloquial physics perspective, there is a vacuum of empty space in between gas atoms.

All the elementary books I had ever read says that gases contains molecules moving randomly in all directions.Atoms/Molecules are much far apart than in solids.Then what fills the space between the atoms/Molecules?Is it a vacuum?

Yes, basically and "classically" its a vacuum. But how you define "vacuum" and "empty space" can get very confused when you consider them carefully. We have intuitive notions about vacuum and empty space that can be confused with what physics has to say about them.

For example, what about light? Would you consider light to break a vacuum? In the lab we never did. :-p Also in quantum you have wave-functions and virtual particles which also can confuse our ideas of vacuum and empty space.

But if we stick to classical and colloquial physics, then I would say yes there is a vacuum of empty space in between the atoms.

If you check the basic, dictionary definition of 'vacuum' you will find that it is a space 'devoid of matter'
So a space containing gas atoms is not a vacuum. Light ! a distraction in this context.
Virtual particles...part of modern physics... modifies our way of describing things but does not change dictionary definitions.
 

Related to Exploring the Space Between Atoms/Molecules in Gases

What is the space between atoms/molecules in gases?

The space between atoms/molecules in gases is the distance between the individual particles that make up the gas. This distance can vary depending on the type of gas and the conditions it is in, but on average it is about 10 times the size of the atoms/molecules themselves.

Why is it important to explore the space between atoms/molecules in gases?

Understanding the space between atoms/molecules in gases is crucial for several reasons. It helps us understand the behavior and properties of gases, such as their compressibility and diffusion. It also allows us to develop new technologies and materials, as well as improve our understanding of chemical reactions and processes.

How do scientists explore the space between atoms/molecules in gases?

Scientists use a variety of techniques and instruments to study the space between atoms/molecules in gases. These include spectroscopy, which uses light to analyze the composition and structure of gases, and electron microscopy, which uses a beam of electrons to visualize individual atoms and molecules.

What have scientists discovered about the space between atoms/molecules in gases?

Through their research, scientists have discovered that the space between atoms/molecules in gases is not empty, but rather filled with constantly moving particles. They have also found that the distance between particles can be affected by temperature, pressure, and other environmental factors.

How does studying the space between atoms/molecules in gases contribute to our understanding of the universe?

Studying the space between atoms/molecules in gases is important for our understanding of the universe because it allows us to better understand the fundamental building blocks of matter. This knowledge can then be applied to other areas of science, such as astrophysics, to help us understand the composition and behavior of objects in the universe.
