The coefficient of thermal conductivity of a metal rod depends on its

Options

  1. Aarea of cross section
  2. Bmass
  3. Cmaterial of the rod
  4. Dlength used

Correct answer

C. material of the rod

Step-by-step solution

The coefficient of thermal conductivity is an intrinsic property of a material. It depends only on the nature of the material and its temperature, and is independent of the dimensions of the rod such as length, area of cross-section, or mass. Answer: material of the rod
