Question

Which best compares Radiation and Conduction? Check all that apply.

• Both can transfer energy through empty space.

• Both can transfer energy through matter

• Both involve the transfer of energy through direct contact

• Both transfer thermal energy by electromagnetic waves.

• Both transfer thermal energy from warm obejects to cooler objects

Answer 1

Answer: The correct answer is- Both transfer thermal energy from warm objects to cooler objects.



Explanation-

Conduction is the mode of transfer of heat from hot body to cold body or from hotter part of a body to colder part without any actual motion of particles.

Radiation is a mode of heat transfer in which heat flows from hot body to cold body without heating the intervening medium.

Thus, both transfer thermal energy from warm objects to cooler objects is the right answer.
