Understanding the Ideal Gas Law

The video tutorial covers the kinetic molecular theory, which describes gases as small particles in constant motion with no significant volume or forces between them. It explains the concept of ideal gases, which perfectly follow this theory, and contrasts them with real gases that only behave ideally under certain conditions. The ideal gas law, PV=nRT, is introduced, allowing for the calculation of gas quantities under various conditions using a constant. The tutorial emphasizes the practical application of this equation in solving problems related to gas behavior.

What does the kinetic molecular theory assume about the volume of gas particles?
