Concept explainers
Interpretation:
The conditions under which supercritical carbon dioxide is formed needs to be determined.
Concept introduction:
Supercritical carbon dioxide is liquid carbon dioxide which is formed above critical temperature and critical pressure of carbon dioxide gas.

Answer to Problem 99A
Above
Explanation of Solution
Supercritical carbon dioxide is a liquid form of
When a gas is made to expand above its critical temperature and critical pressure it changes to a liquid. So when carbon dioxide is expanded above its critical temperature i.e.
