Question

Gita, Vineeta and Suneeta were doing an experiment in which water was to be heated in a 10 ml conical flask. Gita kept the flask near the wick in the innermost part of the candle flame. Vineeta kept the flask in the middle part of the flame. Suneeta kept the flask in the outermost part of the flame. Whose water will get heated in a shorter time?

• A. Gita
• B. Vineeta
• C. Suneeta
• D. Water will get heated with same rate for all of them.

Answer 1

The correct option is C Suneeta

The order of decreasing hotness of three zones is:
outermost > middle > innermost.
The water in the Suneeta's flask will heat up in the shortest time. Since, Suneeta kept her flask in the outermost zone of a flame. The water in the Geeta's flask will heat up for the longest time, as she kept the flask in innermost zone.
Hence, order of time taken by flask in various zones will be:
innermost > middle > outermost.
