物理＜＜＜TRANSFER PROCESSES OF HEAT
發問:
最佳解答:
(i) Air above the heater rises, cool air from the farther side of the room moves towards the heater. (ii) Convection. (iii) Warm air has lower density and rises, cool air with higher density moves towards the heater to replace the rised warm air. Thus a convection current is set up until all the air inside the room is warm.

(i)on the diagram, use arrows to show the path taken by the air which is warmed by the heater. (II)Name this type of energy transfer to the room. (iii)Explain , as fully as you can , why the warmed air moves round the room in this way.最佳解答:
