NEET Physics Heat Transfer MCQ Question
Which of the following statements about heat transfer are correct?
Conduction and convection require a medium for heat transfer, while radiation does not.
Convection occurs only in solids and is driven by density differences.
Radiation transfers energy through electromagnetic waves, which can travel through a vacuum.
Natural convection relies on external forces like fans or pumps to move fluid.
Correct Answer
Detailed Explanation
Conduction and convection indeed require a medium for heat transfer, while radiation can occur in a vacuum as it involves electromagnetic waves. Convection does not occur in solids, and natural convection relies on buoyancy effects, not external forces.
