Critical Point

Subject: Chemistry

Book: General Chemistry

At the critical point, the liquid and gas phases of a substance become indistinguishable, forming a supercritical fluid. Above this temperature and pressure, distinct liquid and gas phases do not exist. Supercritical fluids (e.g., supercritical CO2) exhibit unique solvating properties and are used in decaffeination, extraction, and green chemistry processes due to low toxicity and reduced waste.
