Answer the question:
A cupboard is placed in front of a heater. Air can move through a gap under the cupboard.
Which row described the temperature, and the direction of movement, of the air in the gap ?
air temperature air direction
A cool away from the heater
B cool towards the heater
C warm away from the heater
D warm towards the heater

Solution

As Air in front of heater gets warmer and move upward, to fill that gap fresh air moves through gap towards heater.
Hence option B is correct.

Q. Some models of room heaters have a fan blowing air, instead of having just a heating coil and a reflector. Do you think this could be an advantage? What mode of heat transfer is being used while blowing air in the above heater? Hint:Does blowing the air move the air molecules away from the heater?

In the video humidity also plays an important role. The air inside the cupboard will become more concentrated of water vapour as evaporation takes place while the air present outside the cupboard can hold more water vapour. So the rate of evaporution inside the cupboard will be slower.
