Sand | Density, Heat Capacity, Thermal Conductivity
Density of Sand. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.
