Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Heat transfer occurs via three primary physical mechanisms: conduction, convection, and radiation.
Step 2: Detailed Explanation:
Conduction is the transfer of internal thermal energy through direct microscopic collisions of particles and lattice vibrations without bulk movement of the medium.
It is the predominant mode of heat transfer in stationary opaque solids.
In fluids (liquids and gases), convection dominates due to fluid parcel circulation.
Step 3: Final Answer:
Therefore, conduction is the primary mode of heat transfer in solids.
