Problem 2 (35) A thick, hot iron plate at 100C is placed in contact with a similar, cooler bar at 20C. Calculate the time required for the temperature 1cm into the cooler plate to raise by 10C to 30C. Assume the same (uniform) heat capacity, density, and thermal conductivity for both plates. Both plates are much thicker than 1cm. Show the values of any parameters you looked up for this problem. Hint: Since heat transport is symmetric, the temperature at the interface remains at constant temperature of 600C
