The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 250 J/s. The energy is transferred a distance of 1.7 x 10-3 m through a body whose surface area is 1.8 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin.
