1. & 4. I tried all the buttons and levers, and it works great! Any student with a fundamental knowledge of kinetic theory will be able to use this application. 2. Very high quality. Variables are easy to change, and the visual is terrific. I like the tracking device. 3. The next time I present gases I will use this, and I will link it to my class homepage for the students to play with. It will definitely enhance the concepts for them.
It works great with Internet Explorer, but very poorly or not at all in my Mac version of Netscape v4.72. The JAVA must not be compatible because I get error messages as the applet is loaded.
