What is density definition. The symbol most often used for density is ρ (the lower case greek letter rho ), although the. The units of density depend on the units used for mass and volume, but are usually: It is an intensive property, which is mathematically defined as mass divided by volume:

The average number of individuals or units per unit of space a population density of 500 per square mile a housing density of 10 houses per acre. The degree of opacity (see. It is an intensive property, which is mathematically defined as mass divided by volume:

Energy density simply refers to the number of calories contained in 100 g of food, which is the direct measurement of the energy a given food provides. Put another way, density is the mass of an object divided by its volume. One of the most dense astronomical objects known to us is a black hole.
