A long metallic bar is carrying heat from one of its ends to the other end under steady-state. The variation of temperature $\theta$ along the length $x$ of the bar from its hot end is best described by which of the following figures ?

A

B

C

D

Solution

in previous question $k_1$ = $k_2$ = $k$ and $l_1$ = $x$ and $l_2$ = $l -x$

$\Rightarrow \theta = – mx + C$
