Question

In the following figure, the hand would feel the heat from the candle due to _________.

• A. conduction
• B. convection
• C. radiation
• D. All of the above.

Answer 1

The correct option is B convection

When a candle is lit, the heat from its flame starts to transfer to the air just above the flame. This makes the air hotter, and it rises up. This is due to the process of heat transfer by convection, and the hot air stream is called a convection current. This is the reason why we would feel the stream of hot air hitting our palm when we place our hand on the top of a candle flame.
