Because gases fill their containers, their volume is the same as the internal volume of the container. Liquids are commonly measured using containers, where the volume is marked or else is the internal shape of the container. Examples of instruments used to measure liquid volume include measuring cups, graduated cylinders, flasks, and beakers.
The SI unit of volume is the cubic meter: m 3.Often it is more convenient in chemistry to quote volumes in cubic centimeters: cm 3, or cubic decimeters: dm 3.The cubic decimeter is the preferred scientific name of the quantity previously referred to as the liter.
What Is the Scientific Definition of Volume? In scientific terms, volume is three-dimensional space occupied by a gas, liquid or solid. Scientists measure volume in cubic units, such as liters, cubic meters, gallons and ounces.
Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution.It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100.

The volume of activation is interpreted, according to transition state theory as the difference between the partial molar volumes of the transition state (V) and the sums of the partial volumes of the reactants at the same temperature and pressure, i.e., V = V - (rVR) where r is the order in the reactant R and VR its partial molar volume.
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: =. 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. This explains the usage of ρ (the lower case Greek letter ...
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in ...
Gas Laws One of the most amazing things about gases is that, despite wide differences in chemical properties, all the gases more or less obey the gas laws.The gas laws deal with how gases behave with respect to pressure, volume, temperature, and amount.
The volume of a substance is related to the quantity of the substance present at a defined temperature and pressure. The volume of a substance can be measured in volumetric glassware, such as the volumetric flask and the graduated cylinder. Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure.
