NEET Physics Heat Transfer MCQ Question
Which of the following statements about heat transfer is correct?
Conduction requires a medium for heat transfer, while radiation does not.
Convection can occur in solids as well as fluids.
Radiation can only occur in a vacuum.
Heat transfer by conduction is faster than by convection in all cases.
Correct Answer
Detailed Explanation
Conduction and convection require a material medium, while radiation can occur without one, as it involves the transfer of energy through electromagnetic waves. This is supported by the explanation that radiation needs no medium, while conduction and convection do.
