Qualitative evidence of the microscopic nature of gases is shown by an effect called Brownian motion.
This java applet shows Brownian motion for gas molecules.
(Gas molecules in a container continually collide with one another and with the walls of the container.
Click trace check box to show the trace for one of the molecules (red).
If you click No boundary checkbox,
particles moving to the right edge will appear at left edge again (No collision with the wall).
