Question

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?​

Answer 1

Answer:

The water in the Ramesh's beaker will heat up in a shorter time. This is because the outermost zone of a flame is the hottest zone in which the complete combustion is taking place, while the yellow zone (in which Abida had kept the beaker) is less hot as this is the middle zone which is the zone of partial combustion so it is less hotter than the outermost zone.

Answer 2

Explanation:

The water heated by Ramesh will get heated in a shorter time because he kept his beaker near the hottest zone of the flame. On other hand Abida kept the beaker in the yellow part of the candle flame, which is less hotter than blue part.
