Extracted text: 8. Consider an iron bar, of diameter 4 cm and length 1 m, with specific heat c = 0.437 J/(g K), density p = 7.88 g/cm³, and thermal conductivity k = 0.836 W/(cm K). Suppose that the bar is insulated except at the ends, is heated to a constant temperature of 5 degrees Celsius, and the ends are placed in an ice bath (0 degrees Celsius). Compute the temperature (accurate to 3 digits) at the midpoint of the bar after 20 minutes. (Warning: Be sure to use consistent units.) %3D
