## In This post you will get answer of Q.

Dimensional formula for coefficient of thermal conductivity is (in $Wm^{-1}, K^{-1}$) is

Solution:

## Coefficient of thermal conductivity

$=frac{text{Heat energy $times$ Length}}{text{Area $times$ (temperature difference)$times$ time}}$

$=frac{left[ML^{2}T^{-2}right]left[Lright]}{left[L^{2}right]left[Kright]left[Tright]}$

$=MLT^{-3} , K^{-1}$
