Measurements

A:

Density and mass are mutually dependent physical properties, with density being equal to the amount of mass per unit of volume of any particular object or substance. The mass of any object depends entirely on its overall density, with denser objects having greater mass, for the same volume, than less-dense objects. The mass of an object with uniform composition changes if pieces are added or removed, but its density remains constant. Meanwhile, barring any melting or evaporation, the density of an object tends to change with changes in temperature, while the mass remains the same.
