find out the specific gravity of the lead

Archimedes'' Principle | Physics

The space it occupied is filled by fluid having a weight w fl.This weight is supported by the surrounding fluid, and so the buoyant force must equal w fl, the weight of the fluid displaced by the object is a tribute to the genius of the Greek mathematician and inventor Archimedes (ca. 287–212 B.C.) that he stated this principle long before concepts of force were well established.

How to Calculate the Specific Gravity of a Substance

By Steven Holzner. In physics, a substance''s specific gravity is the ratio of that substance''s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m 3, so its specific gravity is the following:

Density and Specific Gravity Dr. E

Specific gravity is the density of a substance divided by the density of water. The density units cancel, leaving specific gravity a unitless number. Since we often assume the density of pure water to be 1.0 g/mL, the specific gravity usually agrees closely with density. Temperature changes affect the density of
