The option that is an example of heat transfer by conduction is C. person getting warm from an electric blanket.
Conduction involves the transfer of heat through direct contact between materials. In this case, the electric blanket warms the person directly through contact.
The other options involve different types of heat transfer:
- A. Air conditioner cooling the room - this is an example of convection.
- B. Air getting warm from a radiator - this also involves convection, as air currents distribute the heat.
- D. Pavement heating up in the sun - this is an example of radiation.
