The thermal conductivity of a rod is dependent on

Options

  1. Amass
  2. Blength
  3. Carea of cross section
  4. Dmaterial of the rod

Correct answer

D. material of the rod

Step-by-step solution

Thermal conductivity is an intrinsic property of a substance. It depends only on the nature of the material of the rod and its temperature. It is independent of the mass, length, or area of cross-section of the rod.
