2. Intensive and extensive properties - Wikipedia

   en.wikipedia.org/wiki/Intensive_and_extensive...

   The density of water is approximately 1g/mL whether you consider a drop of water or a swimming pool, but the mass is different in the two cases. Dividing one extensive property by another extensive property generally gives an intensive value—for example: mass (extensive) divided by volume (extensive) gives density (intensive).

3. Density - Wikipedia

   en.wikipedia.org/wiki/Density

   Mathematically, density is defined as mass divided by volume: [1] =, where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume , [ 2 ] although this is scientifically inaccurate – this quantity is more ...

4. Mass concentration (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Mass_concentration_(chemistry)

   In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.

5. List of physical quantities - Wikipedia

   en.wikipedia.org/wiki/List_of_physical_quantities

   Mass fraction: x: Mass of a substance as a fraction of the total mass kg/kg 1: intensive (Mass) Density (or volume density) ρ: Mass per unit volume kg/m 3: L −3 M: intensive Mean lifetime: τ: Average time for a particle of a substance to decay s T: intensive Molar concentration: C: Amount of substance per unit volume mol⋅m −3: L −3 N ...

6. Boyle's law - Wikipedia

   en.wikipedia.org/wiki/Boyle's_law

   where P is the pressure of the gas, V is the volume of the gas, and k is a constant for a particular temperature and amount of gas. Boyle's law states that when the temperature of a given mass of confined gas is constant, the product of its pressure and volume is also constant. When comparing the same substance under two different sets of ...

7. Specific quantity - Wikipedia

   en.wikipedia.org/wiki/Specific_quantity

   Volume-specific quantity, the quotient of a physical quantity and volume ("per unit volume"), also called volumic quantities: [2] Specific mass , actually meaning volume-specific mass, or mass per unit volume; same as density .

9. Mass fraction (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Mass_fraction_(chemistry)

   This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...
