A very good and well done simulation of the Ideal Gas Law. All of the buttons and sliders work. The interaction between the molecules and the walls as well as with each other was very well done, with molecules changing direction with even the slightest contact between one another. This simulation would enhance the efectivenss of the teachers ability to teach and the students ability to learn.
It is definately easy to use and almost anyone could start it up and within five minutes know how to use the program.
