calculate the conductive heat flux (W) for the different“feather†materials. Material “A†has a K of 0.036 W/mK andincreases the bird’s x by 2.769 x 10-3 m. Material “Bâ€has a K of 0.17 W/mK and increases the bird’s x by 1.308 x10-2 m. The bird’s internal temperature is 311.0 K (weare assuming that they are endothermic) and the temperature of theground is 260.0 K. The distance from the exterior of the bird’sskin to its core is 0.75 m. When the animal is sleeping the surfacearea of the bird that touches the ground is 1.76 m2.Which of these materials results in the smallest loss of heat dueto conduction?    Â
