Physics And Measurement Question 157
Question: The dimensions of universal gas constant is?
[Pb. PET 2003]
Options:
A) $ [ML^{2}{{T}^{-2}}{{\theta }^{-1}}] $
B) $ [M^{2}L{{T}^{-2}}\theta ] $
C) $ [ML^{3}{{T}^{-1}}{{\theta }^{-1}}] $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
$ \because R=\frac{PV}{T} $
$ =[ \frac{M{{L}^{-1}}{{T}^{-2}}\times L^{3}}{\theta } ]=[ML^{2}{{T}^{-2}}{{\theta }^{-1}}] $
