Answer:

Well, at #"1 atm"# clearly, condensation occurs at #100# #""^@C#.

Explanation:

The normal boiling point of water is #100# #""^@C#. What do I mean by normal boiling point?

Below this temperature, there is the #"saturated vapour pressure"#, i.e. the equilibrium vapour pressure exerted by the liquid phase. Of course, at #100# #""^@C# the equilibrium vapour pressure is #"1 atm"#. Why?
