Description : For demonstrating the convection of heat in a liquid.
Comprises a glass tube of 20 mm outer diameter bent into a
rectangle of size 350 x 250 mm. In the upper short side is a
small tubule for filling, can be mounted vertically by a retort
clamp, boss and stand. Convection currents can be
generated by heating one of the lower corners of the
rectangle. A small amount of Potassium Permanganate
crystals dropped in to the tubule will act as an indicator.
