A medium-compressible state of matter: , staying above Critical Point
.
Also called Fluid alongside with Liquid, Gas and Plasma.
Table 2. Basic comparison of typical gases, liquids and supercritical Fluids
| Density (kg/m3) | Viscosity (µPa·s) | Diffusivity (mm2/s) | |
|---|---|---|---|
| Gases | 1 | 10 | 1 ÷ 10 |
| Supercritical Fluids | 100 ÷ 1000 | 50 ÷ 100 | 0.01 ÷ 0.1 |
| Liquids | 1000 | 500 ÷ 1000 | 0.001 |
