Supercritical CO2

This video shows liquid carbon dioxide being heated to a supercritical fluid. A supercritical fluid is generally understood to be something between a gas and a liquid. Supercritical fluids can only be formed in conditions exceeding the critical point for a substance. The critical point for CO2 is 31.1 C and 1070 psi.

The unique optical effects are called critical opalescence. This phenomenon is caused by density fluctuations that cause fluctuations in the way light refracts through the fluid.

This video was created to supplement our previous supercritical CO2 video that did not have the temperature and pressure overlays.

This video was created in the Critical Fluids Technology and Separations Center in the Ralph E. Martin Department of Chemical Engineering of the University of Arkansas, which is directed by Dr. Jerry King. This video was created for educational purposes.
