One-dimensional steady-state conduction with no internal energy generation is occurring in a plane wall of constant thermal conductivity.

(a) Is the prescribed temperature distribution possible? Briefly explain your reasoning.

(b) With the temperature at x = 0 and the fluid temperature fixed at T (0) = 0°C and T∞ = 20°C, respectively, compute and plot the temperature at x = L, T (L), as a function of h for 10 ≤ h ≤ 100 W/m2 ∙ K. Briefly explain your results.
