$DENSITIES OF THE ELEMENTS Average densities of liquid and solid elements in grams per c.c. at ordinary temperatures unless otherwise stated. For gaseous densities see p. 26. The density of a specimen may depend considerably on its state and previous treatment, eg. the density of a cast metal is increased by drawing, rolling, or hammering. See Koppel in L.B.M. Element.
