compressibility

Compressibility refers to the ability of a substance to change its volume when pressure is applied. In gases, for example, compressibility is high, meaning they can be easily squeezed into a smaller space. Liquids are much less compressible, while solids are typically even less so. This property is important in various fields, including engineering and physics, as it affects how materials behave under different conditions. Understanding compressibility helps in applications like designing pressure vessels, predicting the behavior of natural gases, and ensuring the safety and efficiency of various systems.
