Consider the steady-state temperature distribution within a composite wall composed of Materials A and B.

The conduction process is one-dimensional. Within which material does uniform volumetric generation occur? What is the boundary condition at x = –L_A? How would the temperature distribution change if the thermal conductivity of Material A were doubled? How would the temperature distribution change if the thermal conductivity of Material B were doubled? Does a contact resistance exist at the interface between the two materials? Sketch the heat flux distribution q"_x(x) through the composite wall.
