Question

Dimension of universal gas constant $(R)$ is

• A. $\left[VP{T}^{-1}{n}^{-1}\right]$
• B. $\left[V{P}^{-1}T{n}^{-1}\right]$
• C. $[VPT{n}^{-1}]$
• D. $[VP{T}^{-1}n]$

Answer 1

Answer: (A)

Dimension of universal gas constant $(R)$ is
$\left[VP{T}^{-1}{n}^{-1}\right]$
$\because pV=nRT$
$\therefore R=\frac{pV}{nT}=p{V}_n^{-1}{T}^{-1}$
