Question

Give reason for the following:

If we keep our palm on the side of a burning candle, we don't feel as hot as on keeping it above the flame

Answer 1

Answer:

because of combustion

Answer 2

When we place our palm on the side of the burning candle, convection transfers the energy to the fingers. But when the hand is places on the side, radiation is the heat transfer method here. Thus, the convection heat transfer method aids in transferring large amount of heat energy due to which there is a burning/hot sensation.
