Today, they are rapidly finding new applications as solvents, particularly where low toxicity is desirable, such as decaffeinating coffee and removing pollutants from water.  They make good solvents because they diffuse and permeate like gases, but hold solutes like liquids.  Created by heating a closed vessel partially filled with liquid until the boundary between liquid and gas phases disappears, FTP, identify this type of fluid, which exists at temperatures and pressures above the critical point.
