This action is best shown by mean- of a diagram, as in a glass tube of the form shown in the figure is filled with water andheld in a vertical position, no movement of the water will be noticed,because the two column- .1 and B are of the same weight, and there-for- in equilibrium. Now, if a lamp flame be held near the tube A,the small bubbles of steam which are formed will -how the waterto be in motion, with a current flowing in the direction indicated bythe arrows. The reason for this is, that, as the water in A is heated. S 32.
