What Is the Scientific Definition of Volume? Quick Answer. 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. The most common equation to find volume is mass divided by density. Continue Reading.

Chemistry In chemistry, matter is defined as anything that has rest mass and volume (it takes up space) and is made up of particles. The particles that make up matter have rest mass as well-not all particles have rest mass, such as the photon. Matter can be a pure chemical substance or a mixture of substances.

Volume (thermodynamics) The volume of a thermodynamic system typically refers to the volume of the working fluid, such as, for example, the fluid within a piston. Changes to this volume may be made through an application of work, or may be used to produce work.

- Specific Volume. The specific volume of a substance is a physical quantity determined by the ratio of the volume V to the mass m of a body. The specific volume v of a homogeneous substance is given by the formula v = V/m. Specific volume is the inverse of density. The units of specific volume are 1 m 3 /kg in the International System of Units and 1 cm 3 /g in the cgs system; 1 m 3 /kg = 103 cm 3 /g. 1  Facebook.

Density This relationship between the mass and volume of a substance is what defines the physical property of density: Density = Mass/Volume. Density is defined as the ratio of an object's mass to its volume, as shown in the equation above.

Density The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.

Gas This specific number of gas particles, at standard temperature and pressure (ideal gas law) occupies 22.40 liters, which is referred to as the molar volume. Avogadro's law states that the volume occupied by an ideal gas is proportional to the number of moles (or molecules) present in the container.

Questions and Answers The equation is fairly simple. The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*10 23 atoms/ mole. It can also be molecules per mole.

A substance has a definite volume but an indefinite shape. Is the substance a solid, a liquid, or a gas? Best Answer: Definition of a solid is a substance with a definite volume and a definite shape. Liquids have a definite volume and an indefinite shape. Gases have an indefinite volume and an indefinite shape. The answer you are looking for is: A liquid. Hope this helps you.

- Volume of solid object is defined as three dimensional design of how much space it occupies and is defined numerically. Single dimensions and two dimensions shapes like straight line or square, circle, triangle have zero volume in three dimensional space. Some basic units of volume are Cubic.

Volume The density of an object is defined as the ratio of the mass to the volume. The inverse of density is specific volume which is defined as volume divided by mass. Specific volume is a concept important in thermodynamics where the volume of a working fluid is often an important parameter of a system being studied.

Volume Volume is an important technical analysis tool to learn and understand how to apply to price movements. Volume increases every time a buyer and seller transact their stock or futures contract. If a buyer buys one share of stock from a seller, then that one share is added to the total volume of that particular stock.

How to Calculate Volume How to Calculate Volume. The volume of a shape is the measure of how much three-dimensional space that shape takes up. You can also think of the volume of a shape as how much water (or air, or sand, etc.) the shape could hold if it was filled completely.

Atomic Volume Definition Definition: The atomic volume is the volume one mole of an element occupies at room temperature. Atomic volume is typically given in cubic centimeters per mole-cc/mol. The atomic volume is a calculated value using the atomic weight and the density using the formula: atomic volume = atomic weight/density. By Anne Marie Helmenstine, Ph.D.

solid state, state of matter. (chemistry) the three traditional states of matter are solids (fixed shape and volume) and liquids (fixed volume and shaped by the container) and gases (filling the container) any solid substance (as opposed to liquid) that is used as a source of nourishment.

Molar volume Molar volume. The molar volume, symbol Vm, is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ).

Abundance of the chemical elements Volume-fraction is a common abundance measure in mixed gases such as planetary atmospheres, and is similar in value to molecular mole-fraction for gas mixtures at relatively low densities and pressures, and ideal gas mixtures. Most abundance values in this article are given as mass-fractions.
