These models are for experimenting with and having fun.

By clicking and holding a stationary particle you can drag the particle back to give it energy. This is recorded on screen as Energy.
Temperature is a measure of the average kinetic energy of the molecules.

The number of collisions between different coloured balls is counted (equivalent to a reaction).

To stop the animation control-click in the window.

Vary Temperature
This model allows you to experiment by changing the Temperature in a gas

Other models:
Constant Mass & Pressure

Experiment:

  1. Try releasing the ball with a given energy and stopping it after a set time.
  2. Record the number of collisions.
  3. Repeat with a different amount of energy.

Questions:

  1. Can you explain the difference?
  2. Can you describe how this model differs from real life?
  3. Which of the differences in Qu.2 are significant?
