The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured.
How many kilocalories per gram are there in a 5.2-g peanut if the energy from burning it is transferred to 0.485 kg of water held in a 0.085-kg aluminum cup, causing a 54.9°C temperature increase?
Specific heat of water= 1kcal/Kg degrees C
Specific heat aluminum= 0.215kcal/Kg degrees C
A 50 KW electric furnace measure 1.2m x 1.0m x 0.8m. When the temperature inside the furnace is 1520 oC, a block of aluminum with a mass of 300kg and a temperature of 16.5 oC is placed inside. Assuming the heat loss from the furnace walls is 500 Watts per m2, 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.
