GCSE Physics P1 Question

  • 0 votes

A wood burning stove is used to heat a room.

The fire in the stove uses wood as a fuel. The fire heats the matt black metal case of the stove.

The air next to the stove is warmed by infrared radiation.

How does the design of the stove help to improve the rate of energy transfer by infrared radiation? (2 marks)

I found this question in a past paper but I can't find the mark scheme for it: (Physics P1 Higher Tier. Wednesday 20th June 2012) and it would be really helpful if you could let me know.. Thanks :)

Black is a good emitter of radiation and also matt surfaces are better emitters.

The matt, black metal case is very good at absorbing infrared radiation and also a good emitter therefore the design is good warmer up the house quicker.
