13. 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?
The outermost part of the flame is the hottest region of the flame. Hence, water kept near it will get heated faster i.e in shorter time.
Therefore, the water in Ramesh's beaker will get heated in a shorter time.
