Question

in the image below, where is convection taking place?
options: a, b, c (with corresponding diagram of a pot on a flame, showing heat transfer with labels a, b, c and convection currents in the liquid)

Explanation:

Convection is the transfer of heat through the movement of fluids (liquids or gases). In the image, option B shows the movement of water (a liquid) in a circular pattern (convection currents). Option A is the handle of the pot (heat transfer here would be conduction if through the solid handle material, but the question is about convection). Option C shows heat transfer by radiation (the wavy lines represent infrared radiation).

Answer:

B
