The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 240 J/s. The energyis transferred a distance of 2.0 x 10^-3 m through a body whosesurface area is 1.6 m^2. Assuming that the thermal conductivity is that of body fat (k = 0.20 J/(s·m·degrees C)),determine the temperature difference between the capillaries and the surface of the skin.
a. 9.2 degrees C
b. 5.4 degrees C
c. 1.5 degrees C
d. 6.9 degrees C
e. 3.7 degrees C
