Kompressibilitás

Kompressibilitás refers to the property of a substance to change its volume when subjected to a change in pressure. It is a measure of how much the volume of a given mass of a substance decreases when the pressure applied to it is increased. For gases, kompressibilitás is generally high, meaning their volume can be significantly reduced by increasing pressure. This is because the molecules in a gas are far apart and have a lot of free space between them. Liquids, on the other hand, have a much lower kompressibilitás, as their molecules are closer together and less compressible. Solids are typically considered incompressible for most practical purposes, although they do exhibit a very small degree of kompressibilitás. The inverse of kompressibilitás is the bulk modulus, which represents a substance's resistance to compression. A substance with high kompressibilitás has a low bulk modulus, and vice versa. Understanding kompressibilitás is important in various fields, including fluid dynamics, material science, and engineering, for applications such as designing hydraulic systems, predicting the behavior of gases under pressure, and understanding the properties of materials.
