Kinetic Theory Model

Product Code : SCL-CLE-12875

Quick Answer: The Kinetic Theory Model is apparatus for illustrating the kinetic theory of gases qualitatively, in which a 4-12V DC electric motor vibrates a small platform that sets steel balls moving inside an acrylic tube.

Last updated: October 2026

Key Features

• Electric motor running at 4-12V DC
• Motor vibrates a small platform inside an acrylic tube
• Steel balls move within the tube as the platform vibrates
• More violent vibration simulates a rise in gas temperature
• A heavier float simulates a rise in gas pressure
• Supplied with balls, a polystyrene foam float and a manual

About This Product

The model gives a qualitative picture of the kinetic theory of gases. The steel balls set moving by the vibrating platform act like gas particles: more violent vibration simulates a higher gas temperature, while increasing the weight of the float simulates a higher gas pressure.

Frequently Asked Questions

What voltage does the motor run at?

The electric motor runs at 4 - 12V DC.

How does the model show changes in temperature and pressure?

Increasing the violence of vibration simulates an increase in gas temperature, and increasing the weight of the float simulates an increase in gas pressure.

What is supplied with the model?

It is supplied with balls, a foam float and a manual.
