Which consequence results when supercritical carbon dioxide leaks through a seal?

A)Endothermic expansion quickly cools components.
B)Pressure increase due to vaporisation.
C)The seals quickly regain flexibility.
D)Material stiffening from rapid oxidation.

💡 Explanation

The fluid expands rapidly undergoing Joule-Thomson expansion, as pressure drops below critical point. This results in cooling and possible icing because the rapid expansion absorbs heat. Thus rather than increased pressure due to 'vaporisation', cooling occurs.
