Kinetic Theory Model Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-9184
Jlab Export is a leading Kinetic Theory Model Manufacturer,and suppliers in India
This kinetic theory model shows gas molecules as metal spheres thrown about inside a wide perspex tube. A piston at the bottom is vibrated by a low-voltage motor in the box below, and a speed control sets how hard it shakes. Turning the speed up makes the spheres fly higher and faster, like a gas being heated.

Classroom Demonstrations of Gas Behaviour
At low speed the spheres jostle near the piston, like a cool, dense gas. Raising the speed spreads them higher up the tube, which models a rise in temperature. Students see that each sphere moves at random in both direction and distance, and that collisions keep changing every path.
Teachers often follow the model with measurements on real gases. A Boyles Law Apparatus shows pressure rising as volume falls at fixed temperature. A Charles Law Apparatus shows volume growing with temperature at fixed pressure. The model then explains both results through more frequent or harder collisions of molecules with the walls.
Frequently Asked Questions
What does the motor speed stand for in the model?
The speed of the vibrating piston stands for the temperature of the gas. Faster vibration gives the spheres more kinetic energy, so they rise higher and strike each other and the tube walls more often.
How can a large class see the spheres clearly?
Light the tube from the side and put a black background behind it. The metal spheres then stand out bright against the dark, and the whole class can follow their movement.
Why are the movements random?
Each sphere is struck by the piston and by other spheres at slightly different times and angles. After a few collisions its path cannot be predicted, which is how kinetic theory pictures the molecules of a gas.
How does this model differ from the other kinetic theory models?
This version has metal spheres in a wide perspex tube, driven by a piston and a low-voltage motor with speed control. The Kinetic Theory Model Polystyrene Piston adds floats whose weight models gas pressure. Another Kinetic Theory Model is a large 6 V AC model with polystyrene balls.
Which lessons does it support?
It supports lessons on the particle model of gases, temperature as the average kinetic energy of molecules, gas pressure from collisions, and the spreading of a gas. It suits school and first-year college physics and chemistry.
