To strengthen your claim and to understand gas particle behavior further you will be able to add detectors to your computer model. You will be able to design the detectors that you will be using ,as well. What kind of data would be most useful for the detectors to report? Some examples are:

• How long it takes before a particle reaches the detector? 
• What is the average number of particles that have been at the detector since it was first turned on?
• What is the concentration of particles near the detector?
• Are there any particles near the detector?
• Which direction are particles traveling when they pass the detector?
• What is the temperature of the gas (average speed of the particles) at the detector?
