Q. The dimensions of thermal resistance are
A) $M^{- 1}L^{- 2}T^{3}K$
B) $ML^{2}T^{- 2}K^{- 1}$
C) $ML^{2}T^{- 3}K$
D) $ML^{2}T^{- 2}K^{- 2}$
Explanation
(a) Thermal resistance
$= \frac{l}{KA} = \left\lbrack \frac{L}{MLT^{- 3}K^{- 1} \times L^{2}} \right\rbrack = \lbrack M^{- 1}L^{- 2}T^{3}K\rbrack$
