In addition, there is no surface tension in a supercritical fluid, as there is no liquid gas phase boundary. By changing the pressure and temperature of the fluid, the properties can be "tuned" to be more liquid like or more gas like.
Overview. mon components of a phase diagram are lines of equilibrium or phase boundaries, which refer to lines that mark conditions under which multiple phases can coexist at equilibrium.

Water phase diagram showing the supercritical state. The properties of supercritical water are very different from ambient liquid water.
Supercritical fluids Supercritical fluids
Carbon dioxide (CO 2) is the most widely used supercritical fluid. This is because CO 2 is cheap, chemically inert, non toxic, non flammable and readily available at high purities and at low costs.

b The metastable phases (Ice Ic, ice IV, Ice IX and Ice XIII) do not belong in a phase diagram. However, Ice Ic (cubic ice) has been found in the hexagonal ice phase space below 80 °C, ice IV has been found within the ice three, ice five and ice six phase spaces and Ice IX and Ice XIII have been found within the ice two phase space.

MAKE SURE YOU ARE WEARING SAFETY GOGGLES FOR THIS STEP OR YOU WILL GET SQUIRTED WITH SOLVENT IN YOUR EYE. With a syringe, suck up some solvent and squirt it GENTLY into the manuclave over the gels to create a bath for the gels to wade in while you finish setting the vessel up.

At critical conditions, the molecular attraction in a supercritical fluid is counterbalanced by the kinetic energy. In this region, the fluid density and density dependent properties are very sensitive to pressure and temperature changes.
