Transmission Of Heat Question 42
Question: The dimensions of thermal resistance are
Options:
A) $ {{M}^{-1}}{{L}^{-2}}T^{3}K $
B) $ ML^{2}{{T}^{-2}}{{K}^{-1}} $
C) $ ML^{2}{{T}^{-3}}K $
D) $ ML^{2}{{T}^{-2}}{{K}^{-2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Thermal resistance $ =\frac{l}{KA}=[ \frac{L}{ML{{T}^{-3}}{{K}^{-1}}\times L^{2}} ]=[{{M}^{-1}}{{L}^{-2}}T^{3}K] $
