Question

Two students A and B heated the same mass of water on a candle flame. The student A kept the beaker slightly above the flame of the candle and student B kept the beaker close to the wick of the candle.In which case, the water will get heated in the shortest time and why?

Answer 1

The beaker kept slightly above .Because the candle will not get enough 02 for burning if it is kept very close and hence will provide less heat
