Review Conceptual Example 5 before attempting this problem. To illustrate the effect of ice on the aluminum cooling plate, consider the drawing shown here and the data that it contains. Ignore any limitaions due to significant figures. How much heat per second per square meter is conducted through the ice-aluminum combination and through the aluminum by itself? LThe figure shows ice of thickness 0.0050 meter on an aluminum plate of thickness 0.0015 meter. The temperature to the left of the ice is negative 10 degrees Celsius and the temperature to the right of the aluminum plate is negative 25 degrees Celsius. O combination: 6580 J/(s m2), aluminum only: 2400000 J/(s m?) O combination: 2400000 J/(s m2), aluminum only: 2400000 J/(s m2) O combination: 2400000 J/(s m2), aluminum only: 6580 J/(s m2) O combination: 6580 J/(s m2), aluminum only: 6580 J/(s m2)
