Certain gravity would be the ratio on the mass of the material towards the mass of the equal quantity of water; density is the ratio of the mass of a amount of a material to the quantity of that quantity and is expressed in mass for each unit substance, e.
Earlywood and latewood in a softwood; radial watch, expansion rings closely spaced in Rocky Mountain Douglas-fir In temperate softwoods, there typically is really a marked distinction between latewood and earlywood.
