Slide show of a microscopic sample

This interactive program allows to simulate (all) properties of an ideal gas. You can play with its many commands or use the tutorials which have been composed in the 'Learn Mode' of the program. Click on the extensive Slide show or on the figures below to see samples. At the end of the slide show you can visit the explanation panels which accompany the program. They cover all the topics mentioned in the top menu bar, and more.
'Alder': Equalization of
Volume and pressure at T=const
'Charles-Gay Lussac:
Volume and Temp. p=const
'Carnot': Part of
Carnot-cycle, Isotherm
'Collis': Collision of two
balls of gas
