→About Density
*The [[density]] of a substance can change with [[temperature]] and [[pressure]].
*'''Density''' is used in calculating the [[mass]] of an [[object]] given its [[Volume (Space)|volume]], and vice versa.
*For an [[alloy]] the '''density''' of that [[alloy]] is found by [[sum]]ing the [[mass]] of each [[alloy]] divided by the total [[Volume (Space)|volume]]. However, where the [[Volume (Space)|volume]] of each component is known, not the [[mass]] then the [[mass]] is replaced with the [[Product (Maths)|product]] of the [[density]] and [[Volume (Space)|volume]] of each [[alloy]].
