Answer 2

That's because the paper never gets enough ignition temperature as the heat gets transferred to the water continuously.

(ii) The water absorbs that heat before the ingnition temperature of paper is reached since specific heat capacity of water is the higher here.

(iii) The water begins to warm then gradually boil.
