During a skin burn from an oven, approximate the skin and tissue layer to be infinitely thick compared to the damaged layer. The temperature throughout the entire skin and tissue layer is uniform at 33ºC before contact with the oven, and the surface layer of skin increases to the temperature of the oven, 200ºC, instantaneously upon contact. Find the depth of the damaged layer of skin after 2 seconds of exposure to the oven temperature. Consider skin as being damaged when it reaches 62ºC. The thermal diffusivity of skin is 2.5 x 10-7 m2/s.
