## Question

### 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
