összvolumen

Összvolumen is a term used to describe the total volume of a system—the three‑dimensional space that its matter occupies. It is commonly expressed in cubic meters or liters and applies to a wide range of contexts, from individual objects and liquids to larger regions in physics, engineering, chemistry, geology and mathematics. The concept encapsulates the size or extent of a body or a mixture in a given state of temperature and pressure.

In chemistry and related fields, the total volume of a mixture is often discussed in relation to volume additivity. If the volumes of the pure components were simply additive, the total volume would be the sum of the components’ volumes. In practice, interactions between molecules can cause a volume change on mixing (ΔV_mix), so the actual Összvolumen may be smaller or larger than the sum of the component volumes. The sign and magnitude of ΔV_mix depend on the specific substances and conditions.

In mathematics and physics, the term also refers to the three‑dimensional measure of a region, i.e., its volume in Euclidean space, as defined by standard integral or geometric methods. In applied sciences, Összvolumen is used together with other properties such as density, porosity or saturation to characterize systems like ponds, soils, porous media or reservoirs.

Measurement can be performed by displacement for irregular solids, by geometric calculation for regular shapes, or by calculating from mass and density for homogeneous substances. Understanding Összvolumen is important for dosing, packaging, material design, and modeling of physical processes.
