Question

Which method of heat transfer transmits heat from the sun to the road?

a.Radiation, because electromagnetic waves transfer the heat
b.Radiation, because movement of air particles transfer the heat
c.Conduction, because heat is transferred through a fluid in motion
d.Conduction, because heat is transferred in the absence of a medium

Answer 1

The correct heat transfer method from the sun to the road is radiation, which uses electromagnetic waves to transfer heat without requiring a medium.

Step-by-step explanation:

The method of heat transfer that transmits heat from the sun to the road is radiation. This is because radiation does not require a medium to transfer heat. Instead, it involves the transmission of energy through electromagnetic waves. The sun's energy reaches Earth and its roads through the vacuum of space, where conduction and convection cannot occur because these methods require the presence of material to transfer heat. Radiation can occur through empty space, which is how sunlight travels and heats the road.

Therefore, the correct answer is: a. Radiation, because electromagnetic waves transfer the heat.
