Physics And Measurement Question 72

Question: The dimensions of coefficient of thermal conductivity is

[MP PMT 1993]

Options:

A) $M L^{2} T^{- 2} K^{- 1}$

B) $M L T^{- 3} K^{- 1}$

C) $M L T^{- 2} K^{- 1}$

D) $M L T^{- 3} K$

Show Answer

Answer:

Correct Answer: B

Solution:

$\frac{d Q}{d t} = - K A (\frac{d θ}{d x})$
$\Rightarrow$ [K] = $\frac{[M L^{2} T^{- 2}]}{[T]} \times \frac{[L]}{[L^{2}] [K]}$ = $M L T^{- 3} K^{- 1}$
