hiiiiii
As we all know at normal boiling point, vapor pressure of water is equal to atmospheric pressure. Vapour pressure of water is pressure exerted by its vapor(in dynamic equilibrium with water) on the surface of water.
We also know that liquid water doesn't change it's phase untill it reaches 100°C except evaporation is always there.
So, can I assume that just before it starts boiling (in saturated water), the entire 1 atmospheric pressure is only due to the part of water which is evaporated before? As boiling is not started yet!!
I hope it's help you
