Registed user can get files related to this applet for offline access.
Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
If java program did not show up, please download and install latest Java RUN TIME

Matter can be either in solid,liquid or gas state due to the change in temperature.
This is an animation of 3D particle model for such situation.
Because we need to add enough particles and calculated all the interactions between any two particles. the animation is a slow motion to illustrate a real situation.



The color for the particle is varying according to the Z coordinate (to help you see the whole structure more easierly)
You can change the gravity and Temperature of the system.
You can also drag the slide on the right (up and down) to see the locations for particles at the selected Z position. (shown in gray at the top:zmax)
The following image shows particles in solid state and form a fix structure. Because of the gravity, there are more particle near the bottom of the container.


If there is no gravity, you will find something similar to the followong
