Ideal Gas Law Simulation

The application is quite good.  I found navigating through the graphs and situation responses a little unclear and clunky.  Having the instructions pop up immediately upon entering the site would make the experience better instead of them being in a link.

I liked the flexibility/variables offered by the site.  The way it is constructed without much explanation would require that it be used as a demonstration device in the classroom, and not left to the student as a tutorial, without sufficient background understanding.
