The length of the ice block is L1 = 0.00484 m and its temperature is T1 = -11.0 °C. The aluminum block is L2 = 0.00139 m long and has a temperature of T2 = -23.9 °C. Ignore any limitations due to significant figures. Calculate the heat per second per square meter that is conducted through the ice-aluminum combination. Do not enter unit.
