# ) A rod of length l with thermally insulated lateral surface consists of material whose heat conductivity Coefficient varies with temperature as k=?/T, where a is a constant. The ends of the rod are kept at Temperatures T1 and T2. Find the function T(x), where x is the distance from the end whose temperature is T1, and the heat flow density.

Temperature of all section of the rod becomes constant.
kA = constant for all cross-section.
Solve it.

from  fourier law of heat conduction we can solve this.
