supercritical fluid -> υπερκρίσιμο υγρό, υπερκρίσιμο ρευστό

A supercritical fluid is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve materials like a liquid. In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical fluid to be "fine-tuned". Supercritical fluids are suitable as a substitute for organic solvents in a range of industrial and laboratory processes. Carbon dioxide and water are the most commonly used supercritical fluids, being used for decaffeination and power generation, respectively.

Υπερκρίσιμα υγρά. Υπερκρίσιμο υγρό είναι κάθε συστατικό που βρίσκεται σε θερμοκρασία και πίεση πάνω από το θερμοδυναμικά κρίσιμο σημείο του.
