Q. The dimensions of universal gas constant is
A) $\lbrack ML^{2}T^{- 2}\theta^{- 1}\rbrack$
B) $\lbrack M^{2}LT^{- 2}\theta\rbrack$
C) $\lbrack ML^{3}T^{- 1}\theta^{- 1}\rbrack$
D) None of these
Explanation
$\because R = \frac{PV}{T} = \left\lbrack \frac{ML^{- 1}T^{- 2} \times L^{3}}{\theta} \right\rbrack = \lbrack ML^{2}T^{- 2}\theta^{- 1}\rbrack$
