Which of the following is a rapid process?
Correct answer: B. Radiation
- A. Conduction
- B. Radiation
- C. Convection
- D. All of these
Explanation
Conduction, convection, and radiation are the three primary modes of heat transfer. Conduction is the transfer of heat between objects that are in direct contact with each other. This process occurs relatively slowly as it depends on the thermal conductivity of the materials involved. Convection is the transfer of heat through the movement of fluids or gases. It occurs due to the motion of fluids or gases and can be relatively rapid, but not as fast as radiation. Radiation is the transfer of heat through electromagnetic waves, and it occurs at the speed of light. It is a very rapid process compared to conduction and convection. Therefore, option (B) Radiation is the correct answer.
