A supercritical fluid is defined as one that is above its thermodynamic critical point, as identified by the critical pressure (p c) and critical temperature (T c). Supercritical fluid behavior can be peculiar because of the variation of thermophysical properties such as density and specific heat near and at the critical point. Supercritical fluids have some properties similar to liquids (e.g., density), and some properties that are comparable to those of gases (e.g., viscosity). Thus, they cannot be considered either a liquid or a gas.
