You place a bottle of water over a burner and bring it to a rapid boil. You then cover the bottle with a stopper and remove it from the heat. As soon as the water stops boiling you push the stopper snugly into the opening to seal the bottle, which now contains no air, only liquid water and steam. If you let the sealed bottle cool to room temperature,
A. the pressure will remain the same as when you sealed it since the rate at which water evaporates balances the rate at which it condenses.
B. a partial vacuum will form since the vapor pressure of water at room temperature is much less than atmospheric pressure.
C. the top will blow off of the bottle as water continues to evaporate, causing the pressure inside to rise.
D. the water will begin to boil again since a vacuum will form and water in a vacuum boils.
