This apparatus is used to study the motion & behaviour of molecules in gases. A small electric motor running at 4 - 12V DC vibrates the small platform inside the transparent tube so that the set of many small steel balls inside vibrate violently inside the tube.
An increase in violence of the vibration simulates an increase in the gas temperature and an increase in the weight of the “float” simulates an increase in the gas pressure.
Supplied with instruction manual, balls and 2 polystyrene “floats”.
Can also be to observe Brownian Motion, Boyle’s Law & Charles’ Law.
