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 consisting of four different materials, the with the same thickness. The temperatures atthe interface between the of the materials are given in. Rank the four materials in order of increasing thermal conductivity. Indicate ties where appropriate.
