Great curiosity 

Your Answer :- We see drop of the water on Inside the lid .


Reason/Explanation :-
 

The heat is transferred here through metal heat conduction 

We know that while boiling water in a teapot , At almost 100
° , It produces vapor .
The vapors now come in contact with lid, as lid upper surface temperature is lower then inner surface temperature but hotter than surrounding.

Assume inner temperature is 100° and lid temperature is 70° C. Hence vapors comes contact into lid at 70° . In result it will condensed into water drops.

Hence the lid on the teapot initially on the outer temperature and act as condenser.


Hope it Helps :-)
