Erick lights two fires. Above Fire 1, he puts a long piece of iron and lays a steak on top. Above the Fire 2, he puts a slab of rubber and also lays a steak on top of that.

Which of the following is most likely to happen?

a)

The steak above Fire 1 cooks well because iron insulates the meat.

b)

The steak above Fire 2 cooks well because of conduction.

c)

The steak above Fire 1 cooks well because iron is a good conductor of heat.

d)

The steak above Fire 2 cooks well because there is more radiation.
