Question

The dimension of the coefficient of thermal conductivity are

Solution

Correct option is

 

The coefficient of thermal conductivity is defined as the rate flow of heat energy per unit area of cross-section per unit temperature gradient. The dimension of rate of flow of heat are ML2T-2/T = ML2T-3. The dimensions of area L2 and the dimensions of temperature gradient are = dimensions of thermal/dimension of length = Kl-1. Hence the dimensions of the coefficient of thermal conductivity are
