The phase of matter that exists above the critical temperature.
a fluid kept under pressure so that it behaves like a liquid although above its boiling point
a high-pressure, high-temperature state of matter best described as a liquid-like gas, and a marvelous solvent
a material,liquid or gas,produced by heating a gas above its critical temp
a material which can be either liquid or gas, used in a state above the critical temperature and critical pressure where gases and liquids can coexist
a substance that has some of the properties of a liquid and some of the properties of a gas
a substance which is above its critical temperature, Tc and pressure, Pc
A fluid state that occurs when the pressure and temperature exceed the substance's critical pressure and critical temperature. Supercritical fluids fill their containers like gases but dissolve substances like liquids, which makes them very useful as solvents. Their density and other properties are intermediate between gases and liquids.
A supercritical (or critical) fluid is a liquid/gas under extreme pressure. These supercritical fluids have unique characteristics, the density of a liquid and the mobility of a gas. Supercritical fluids exist deep inside some planets; for example, there is supercritical water deep inside the Earth.
Supercritical fluids are highly compressed gases which combine properties of gases and liquids.
A supercritical fluid is any substance at a temperature and pressure above its thermodynamic critical point. It has the unique ability to diffuse through solids like a gas, and dissolve materials like a liquid. Additionally, it can readily change in density upon minor changes in temperature or pressure.
