1. A stainless steel spoon (k = 15 W/m-K) is partially immersed in boiling water at 100C in a kitchen at 20C. The handle of the spoon has a cross section of 2 mm 10 mm and extends 150 mm in the air from the free surface of the water. If the heat transfer coefficient on the exposed surfaces of the spoon handle is 20 W/m-K, determine the temperature of the spoon at its end. What is the temperature at the end of a silver (k = 430 W/m-K) spoon? Spoon Boiling water 150 mm
