Three States of Matter Simulation
1. Add heat or remove heat by clicking on the corresponding buttons.
2. Remove heat from the system of particles until they coalesce. Write down the arbitrary temperature at which this occurs.
3. Add heat until the temperature is approximately 280 K and describe the behavior of the particles in terms of their speed(s) / their mean separation distance.
4. Add heat until the temperature is around 400 K and describe the particle behavior in terms of their speed(s) / their mean inter-particle distance.
5. Propose a molecular kinetic model that could be a suitable way of describing states of matter in real life, based on your experiences with this computer model.
Other interesting facts
1. This model follows the color association of BLUE corresponding to low temperature and RED corresponding to high temperature.
2. The gravity slider allows the user to experience the effects of gravity.

The Molecular Dynamics JavaScript Performance Model was formulated by Wolfgang Christian and Paco, and computes the trajectory of particles acted on by a Lennard-Jones force. This simulation is designed to test the speed of a computationally intensive JavaScript model. The user can vary the number of particles, the number of frames per second, and the number of Verlet steps between frames. The actual number of Verlet steps per frame is shown.
If the model becomes unstable, reset the model and reduce the computational (Verlet) timestep Δt.
