Physics And Measurement Question 47
Question: Dimensional formula for latent heat is
[MNR 1987; CPMT 1978, 86; IIT 1983, 89; RPET 2002]
Options:
A) $ M^{0}L^{2}{{T}^{-2}} $
B) $ ML{{T}^{-2}} $
C) $ ML^{2}{{T}^{-2}} $
D) $ ML^{2}{{T}^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ Q=mL\Rightarrow L=\frac{Q}{m} $ (Heat is a form of energy) = $ \frac{ML^{2}{{T}^{-2}}}{M}=[M^{0}L^{2}{{T}^{-2}}] $
