Thermodynamics - Explaining the Critical Point

This experiment demonstrates the behavior of carbon dioxide around the critical point. It shows the transition of a liquid-vapour-mixture to the supercritical state and back. Watch how the phase boundary disappears and reappears. There is also a short description of the process in a P-T-diagram. Created by mechanical engineering students and the Centre for New Meda at Bergen University College, Norway. www.hib.no/en/
