The dif-ference in the height of thetwo columns affords a measureof the relative density of theliquid within the two arms,and indirectly of the expansion which the former under-goes when heated. 135. Expansion of Gases. — The mere fact of the expan-sion of gases may be demonstrated by means of apparatus. Fig. 136.
