t 2. Weiffh an iron nail in air. Mass (W)= SPECIFIC GRAVITY. 145 Tie a thread to it, suspend it from the scale-pan of a balanceand weigh it when surrounded with water (Fig. 115). Mass (W1)= 1 Therefore W - Wj = the loss in weight in water. = the buoyancy of the water. = the mass of water equal in… … Flo. 115. 146 PHYSICAL SCINNCK. Experiment 3- Find in the same way the specific gravities of pieces ofglass, lead, rock, etc. If the solid is soluble in water, its specific gravity may beobtained by finding, as above, the ratio of its mass to thatof an equal volume of some liquid in which it is not…
