particle model for solid/liquid/gas states in 3D

[Fu-Kwun Hwang]

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.

• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.

Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

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
