1. The problem statement, all variables and given/known data How does the boiling process at supercritical pressure differ from the boiling process at subcritical pressure? 2. Relevant equations N/A 3. 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.
