Abida and Ramesh were doing an experiment in which water was to be heated in a beaker. Abida kept the beaker near the wick in the yellow part of the candle flame. Ramesh kept the beaker in the outermost part of the flame. Whose water will get heated in a shorter time?

Water in Ramesh's beaker will heat faster.

In a candle flame, outer most zone is the hottest part (blue part) and inner most zone (yellow part) is the coldest part.

Since Ramesh uses the hottest part of flame to heat, water in his beaker will get heated first.
