Homework Statement



How does the boiling process at supercritical pressure differ from the boiling process at subcritical pressure?

Homework Equations



N/A

The Attempt at a Solution



I know that the critical point is the point on a P-v diagram where the saturated liquid and saturated vapor curves meet.

At subcritical pressures, we could have a saturated liquid where the addition of energy would cause some of the liquid to vaporize into a saturated vapor without an increase in temperature. This is boiling.

Can boiling even occur at supercritical pressures? I didn't think this was possible.

I thought that at supercritical pressures, adding energy would cause a single-phase region to expand and become more dense and the temperature would increase. Is this correct? Any additional information would be appreciated. Thanks!
