An equation is derived for the density of a substance in the surface layer of a liquid under its own saturated vapor, an equation from which expressions can be found for the surface tension and for the thickness of the surface layer. On the basis of irreversible thermodynamic processes, an ...

e.g. The region has a very high population density. 该地区的人口密度很高。 2.(物质或物体的)密度 In science, the density of a substance or object is the relation of its mass or weight to its volume. e.g. Jupiter's moon Io, whose density is 3.5 grams per cubic centimetre, is all ...
Noun1.relative density- the ratio of the density of something to the density of a standard density,denseness- the amount per unit size specific gravity- the density of a substance relative to the density of water vapor density,vapour density- the density of a gas relative to the density of...

Specific gravity (SG) is the ratio between the density of a substance and the density of water. If the temperature is not specified, it is assumed to be water at 3.98ºC and therefore has a density of 0.999972 g/cm3or 999.972 kg/m3. ...
Apparent densityis the dry mass per unit volume of a substance under natural conditions. It is defined by: (2.2)ρ0=mV0 In this formula: ρ0is the apparent density (kg/m3); mis the mass under dry conditions (kg); ...
Free WordPress Plugin: This volume calculator uses a density formula ρ = m/V to find densities of different substances and objects. It calculates the third one for two given values - density, mass, or volume of a substance.www.calculator.io/density-calculator/ ...
Write the equation for density, given both the dynamic and kinematic viscosity of a substance. The equation is: Density = Dynamic viscosity / Kinematic viscosity Step 2 Substitute both the values for dynamic and kinematic viscosity into the equation for density. For example, consider a fluid with...
Density is the mass of a substance per unit volume. In the form of an equation, this means: \(\rho = \frac{m}{V}\) The Greek letter rho, ρ, is traditionally used to represent density; m is the mass; and V is the volume. The units of density are kg pe...
