A 50 KW electric furnace measure 1.2m x 1.0m x 0.8m. When the temperature inside the furnace is 1520 o C, a block of aluminum with a mass of 300kg and a temperature of 16.5 o C is placed inside. Assuming the heat loss from the furnace walls is 500 Watts per m 2 , how long will it take to heat the aluminum block to the furnace temperature? Assume that the specific heat of aluminum is 0.9 KJ/kg-K
