(i) In conduction, matter is not transported with heat; while in convection, matter is transported with the heat.
(ii) Convection takes more heat upwards. Towards the top, the air gets heated by convection. Therefore, the hand above the flame feels hot. On the sides, however, there is no convection and air does not feel as hot as at the top.
