Question

The table describes two methods of heat transfer.

Methods of Heat Transfer

Method A |

Molecules of the medium move during heat transfer.
——————————————————-
Heat is transferred in gases and liquids by this method.
——————————————————-

Method B |

Transfer of heat is through waves like a radio and light waves.
——————————————————-
Heat is transferred through space by this method.
——————————————————-

Which statement is correct?

•Method A is convection and Method B is radiation.

•Method A is convection and Method B is conduction.

• Method A is radiation and Method B is convection.

• Method A is radiation and Method
iS conduction.

Answer 1

Answer:

Method A is convection and Method B is radiation.

Step-by-step explanation:

The description of Method A includes "Molecules of the medium move during heat transfer" and "Heat is transferred in gases and liquids by this method." These statements refer to the movement of a fluid due to a temperature difference, which is characteristic of the process of convection.

The description of Method B includes "Transfer of heat is through waves like a radio and light waves" and "Heat is transferred through space by this method." These statements refer to the transfer of energy via electromagnetic waves, which is characteristic of the process of radiation.

Therefore, Method A is convection and Method B is radiation.
