A close look at ,supercritical carbon dioxide,. A pressure vessel made of aluminum and acrylic is filled with pieces of dry ice. The dry ice melts under high pressure, and forms a liquid and gas phase. When the vessel is heated, the CO2 becomes ,supercritical, — meaning the liquid and gas phases merge together into a new phase that has properties of a gas, but the density of a liquid.
