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

Solution

We know that $dQ over dt space equals space KA dθ over dx$
In steady state flow of heat
$dθ space equals space dQ over dt.1 over KA. dx rightwards double arrow straight theta subscript straight H space equals straight theta space equals space straight k apostrophe straight x rightwards double arrow space straight theta space equals straight theta subscript straight H space minus space straight k apostrophe straight x Equation space straight theta space equals space straight theta subscript straight H space minus space straight k apostrophe space straight x space represents space straight a space straight space line$
