(a)
A firewalker runs across a bed of hot coals without sustaining burns. Calculate the heat transferred by conduction (in J) into the sole of one foot of a firewalker given that the bottom of the foot is a 2.90 mm-thick callus with a conductivity at the low end of the range for wood and its density is 300 kg/m3. The area of contact is 25.0 cm2, the temperature of the coals is 700°C, and the time in contact is 1.06 s.
48.5
J
(b)
What temperature increase (in degrees C) is produced in the 7.25 cm3 of tissue affected?

Now wait a minute, I just did the pan with the water. Do this pretty much the same way.
