Question
Which of the following is not a mode of heat transfer?
Answer: Option D
:
D
There are three modes of heat transfer: conduction,convectionand radiation. Any energy exchange between bodies occurs through one of these modes or a combination of them. Conduction is the transfer of heat by physical contact.Convectionuses the movement of fluids to transfer heat.Heat radiationis the transfer of heatenergy through electromagnetic waves. Radiation doesn't require any medium.
Reflection means bouncing of light wave when it strikes an object. It is not a mode of heat transfer.
