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 ...
Density can be defined as the ratio of the mass of an object to the volume. To find the density of an object, simply divide mass and volume. The equation looks like this: D=M/V. Density is an intensive property that depends only on the composition of a substance, not the size of ...

Density is the mass per unit volume of a substance or object. In equation form, density is defined as ρ=mVρ=mV. The SI unit of density is kg/m3. Conceptual Questions 1. Approximately how does the density of air vary with altitude? 2. Give an example in which density is used to...
The key difference between density and concentration is that the density of a substance depends only on the amount of matter within a given volume whereas
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...

The density of the golf ball can then be calculated as ρ = (45 g) (0.001 kg/g) / (3.8×10-5m3) =1184kg/m3 Example 2: Using Density to Identify a Material An unknown liquid substance has a mass of 18.5 g and occupies a volume of 23.4 ml (milliliter). ...
The equation for density is ρ=m/v. In order to measure the density of a substance, you can calculate a regularly-shaped object's volume and proceed from there, measure the volume of a liquid or how much liquid an irregular object displaces in a graduated cylinder, or use a hydrometer ...
Density refers to the compactness of a mass in a substance or material. It can be represented using this formula: {eq}Density = \frac{mass}{volume} {/eq} where mass is in kilograms and volume is in meter cube. In other words, density can be expressed as weight of a substance in kil...
