Q. The dimensional formula for Boltzmann’s constant is
A) $\lbrack ML^{2}T^{- 2}\theta^{- 1}\rbrack$
B) $\lbrack ML^{2}T^{- 2}\rbrack$
C) $\lbrack ML^{0}T^{- 2}\theta^{- 1}\rbrack$
D) $\lbrack ML^{- 2}T^{- 1}\theta^{- 1}\rbrack$
Explanation
$k = \left\lbrack \frac{R}{N} \right\rbrack = \lbrack ML^{2}T^{- 2}\theta^{- 1}\rbrack$
