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?

Certainly, here are the key points:

Ramesh (Outermost Flame):
1. Higher Temperature: The outermost part of the flame (blue zone) has the highest temperature.
2. Efficient Heat Transfer: This zone provides more efficient heat transfer due to its higher temperature.
3. Faster Heating: Placing the beaker in the outer blue part of the flame results in quicker heating of the water due to the higher temperature facilitating rapid heat transfer.

Abida (Yellow Part of Flame):
1. Lower Temperature: The yellow part of the flame has a relatively lower temperature compared to the outer blue part.
2. Slower Heat Transfer: Heat transfer in the yellow part of the flame is less efficient due to the lower temperature.
3. Slower Heating: Beaker placement in the yellow part of the flame results in slower heating of the water due to the lower temperature, causing a delay in reaching the desired temperature.

In summary, Ramesh’s beaker placed in the outer blue part of the flame will heat the water in a shorter time due to the higher temperature and more efficient heat transfer compared to Abida’s beaker placed in the lower temperature yellow part of the flame.
