This app lets you touch the Ideal Gas Law. Molecules bounce off each other as they do in a real gas (like the air). Watch the pressure change as you squish and expand a container (Volume Tab) or as you virtually heat or cool the gas (Temperature Tab). And, if you want to read about the basics of the Ideal Gas Law and what it means, just click on the Overview Tab.By choosing clarity and simplicity over rigor, I introduce the basics of the Ideal Gas Law in a quick and simple way. This app doesn't dive into the deep technical details of the physical properties or thermodynamics of gases. However, if you want to see more technical details I have compiled a list of resources on the support website.
