Kinetic Theory Apparatus
Product Code : SCL-PLE-11820
Quick Answer: The Kinetic Theory Apparatus models the motion of gas molecules with chrome steel spheres and low-density polymer beads agitated inside a transparent acrylic tube by a low-voltage DC motor. Speed is set with a stepless variable potentiometer, and the unit measures 190 mm x 190 mm x 380 mm.

About This Product
Raising the motor speed makes the spheres move faster and spread out, which models how heating a gas increases molecular speed, pressure and volume. Students use it to visualise Brownian motion, diffusion and the difference between the particle arrangements of solids, liquids and gases. Educational Instrument can arrange export supply of the Kinetic Theory Apparatus to France, Egypt, Central African Republic, Cameroon, Kazakhstan and Saint Vincent and the Grenadines.
Frequently Asked Questions
How is the particle speed changed on the Kinetic Theory Apparatus?
A stepless variable potentiometer adjusts the speed of the DC motor that agitates the spheres and beads.
