MCQ

Dimensional Formula of Universal Gas Constant is

✓
$[M{L^2}{T^{ - 2}}{\theta ^{ - 1}}]$
B
$[{M^2}L{T^{ - 2}}\theta ]$
C
$[M{L^3}{T^{ - 1}}{\theta ^{ - 1}}]$
D
None of these

✓

Answer

Correct option: A.

$[M{L^2}{T^{ - 2}}{\theta ^{ - 1}}]$

a
(a) $ R={\frac{PV}{T}} $ $ = \left[ {\frac{{M{L^{ - 1}}{T^{ - 2}} \times {L^3}}}{\theta }} \right] $ $= [M{L^2}{T^{ - 2}}{\theta ^{ - 1}}]$
