By definition vapor pressure seems the pressure of vapor ABOVE the liquid which is in equilibrium with liquid and how the hell we are applying the concept of vapor pressure in open container while discussing boiling? | |

| Jul 6, 2021 at 3:54 | comment | added | Virender Bhardwaj | Say I have a bowl of water let in a box having air at 1 atm. So sooner an equilibrium will get establish between its vapors and liquid then we call it saturation vapor pressure, now I have a 2nd identical bowl kept I a box having very less air (or vaccum) we know at room temperature water will start boiling so more vapors will form so how can we say that vapor pressure will remain the same as in previous case? | |
