From Wikipedia,
the free encyclopedia.
In
chemistry,
materials science, and other
scientific disciplines, a bulk
property of a substance is one
that is independent of the amount
of that substance being measured.
For instance, the
mass of a substance is not
a bulk property, because it
depends on the amount of that
substance being measured; one
cubic meter of lead weighs a
million times as much as a cubic
centimeter of lead. However, both
have the same
density; thus, density is a
bulk property.
Other examples of bulk
properties include
refractive index,
concentration,
half-life,
elastic modulus, and
tensile strength.
The concept is similar to that
of
per capita measurements in
economics.
