Some Basic Concepts Of Chemistry Question 298
Question: The unit J $ P{a^{-1}} $ is equivalent to
Options:
A) $ m^{3} $
B) $ cm^{3} $
C) $ dm^{3} $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
JPa?1; Unit of work is Joule and unit of pressure is Pascal. Dimension of Joule i.e. work $ =F\times L $ $ =ML{T^{-2}}\times L $
$ =[ ML^{2}{T^{-2}} ] $
$ \frac{1}{Pa}=\frac{1}{Pressure}=\frac{1}{\frac{F}{A}}=\frac{1\times A}{F}=[ ML{T^{-1}} ] $
So, JPa?1 $ =[ ML^{2}T^{2} ] $ $ =[ L^{2}\times L ]\ =[ L^{3} ] $ .
