Question
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.
Options
A.
B.
C.
D.
Solution
We know that 
In steady state flow of heat
⇒ θH - θ = k′x⇒ θ = θH - k′x
Equation θ - θH - k′x represents a straight line.
