Question

a the flames transferring heat to the steak
b steam rising to the top of the pan
c the steak absorbing heat from the bottom of the pan
d the iron pan absorbing heat from the steak

Explanation:

Conduction is the transfer of heat through direct contact. Option a is radiation (heat transfer via electromagnetic waves from flames). Option b is convection (heat transfer via fluid movement - steam rising). Option d is incorrect as heat should transfer from pan to steak, not the other way. Option c shows direct contact (steak and pan bottom) for heat transfer, which is conduction.

Answer:

C. The steak absorbing heat from the bottom of the pan
