Thermodynamics: Ideal gas model

[koddball]

Homework Statement

I have some confusion about the ideal gas model. It would be helpful if you can provide an explanation. Thank you!

Relevant Equations

N/A

Do particles have air in between them in the ideal gas model?

I think the answer is 'no, but I am not quite sure about the explanation. Is it because in an ideal gas model, the volume of the particles is negligible? Thank you.

Do you really mean air, or do you just mean empty space?
