A supercritical fluid forms at high pressures and high [[temperature]]s, when a substance no longer has a distinction between a [[liquid]] and a [[gas]].  For example, a supercritical fluid is compressible (like a liquid) but takes the shape of the container (like a gas).  The point on the [[phase diagram]] where a supercritical fluid forms is called the critical point.
