👉 Imagine a substance that flows like a liquid but possesses properties of both liquids and gases, existing in a state between these two forms. This hypothetical fluid, often referred to as a supercritical fluid, exists at conditions of high temperature and pressure where it transcends the conventional boundaries between liquid and gas. It can penetrate the spaces within solids like a gas, allowing it to dissolve materials effectively, yet it maintains a viscosity and surface tension similar to liquids. This unique state makes supercritical fluids incredibly useful in various applications, such as extraction processes in chemistry and pharmaceuticals, where they can selectively dissolve and transport compounds with remarkable efficiency.
