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 :-)
