If water is heated at the supercritical pressure (> 221.2 bar)
Answers
Q. If water is heated at the super-critical pressure (221.2 bar) then what happened?
Answer :
At this point there is no change of state take place because when water is heated at this pressure (or reaches at this critical point) the phase immediately turns into steam without the intermediate stage of evaporation (changing the density working fluid). At this critical pressure, Its unclear to distinguish between the water phase and steam phase.
Therefore, we can say, when water is heated at super-critical pressure that is 221.2 bar, it immediately turns into steam without the intermediate stage of evaporation.

When water is heated at super-critical pressure that is 221.2 bar, it turns into steam without the intermediate stage of evaporation. At this pressure, we cannot differentiate between the water phase and steam phase. In water, the critical point occurs at around 647 K (374 °C or 705 °F) and 22.064 MPa (3200 psia or 218 atm).
