NEET Solved Paper 2019 Question 18
Question: The unit of thermal conductivity is: [NEET 5-5-2019]
Options:
A) $ WmK^{1} $
B) $ ~Wm^{1}K^{1} $
C) $ Jm{K^{b1}} $
D) $ Jm^{1}K^{1} $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ H=\frac{kA}{\ell }({\theta_1}-{\theta_2}) $ $ k=\frac{H\ell }{A\theta } $ $ =\frac{W.m}{m^{2}K} $ $ =Wm^{1}K^{1} $
