Density is a quality that measures mass per unit volume. Mathematically, density is found by dividing an object's mass by its volume. Another way to think of it is as relative heaviness. The Greek letter rho and the Lati... More »

According to the science department at Elmhurst College, the density of an object is how relatively heavy an object is at a fixed volume. Mathematically, the definition of density is mass divided by volume, where the sta... More »

Density is the mass per unit volume of a material, while specific gravity is the density of a material divided by the density of water. Multiplying the specific gravity by the density of water gives the density of a mate... More »

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... More »

The formula to find an object's density is its mass divided by volume. Density is not possible to directly measure. To find the density of an object, it is necessary to find its mass and volume. More »

Some examples of physical properties include things like odors, mass, density, color, conductivity and volume. Physical properties of matter have two main categories: intensive properties and extensive properties. More »
