Question: Heat is transferred from an area where the temperature is 20 C to an area where the temperature is 0 C through a composite slab

Heat is transferred from an area where the temperature is 20 Â°C to an area where the temperature is 0 Â°C through a composite slab consisting of four different materials, each with the same thickness. The temperatures at the interface between each of the materials are given in FIGURE 16-28. Rank the four materials in order of increasing thermal conductivity. Indicate ties where appropriate.
