The temperature at the inner and outer surfaces of a plane wall of thickness L are held at the constant values T₀
and T_L, respectively, where T₀
> T_L: The wall material has a thermal conductivity that varies linearly according to k
 k₀
(1 +
T), k₀
and
 being constants. At what point willthe actualtemperature profile differ most from that which would exist in the case of constant thermal conductivity?
