The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 240 j/s. the energy is transferred a distance of 2.0 x 10^-3 m through a body whose surface area is 1.6 m^2. assuming that the thermal conductivity is that of body fat (k = 0.20 j/(s•m•degrees 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
