Best Answer: Specific Heat is the energy required to raise EACH gram of a material by 1C. This is expressed in J/gC. The temperature change is 82.1C - 30.7C = 51.4C. The Aluminum weighs, not 1g, but 625g. m x c x Î´T = Q 29.5g x 0.45J/g/Â°C x (40 - 25Â°C) Î´T = 199.125 Joules (= 0.199kJ) of heat absorbed. (you can say 0.200kJ) If 8.4kJ was used as in your initial statement, to raise the temp. by 5Â°C, the mass of iron must have been much greater than 29.5g. or, 8.4kJ is an error. 29.5 x 0.45 x 5 = 66.4 kJ.
I have had this furnace for five years. The house is a two story, 900 square feet per level. I keep the temperature at 70 degrees. Our average winter is 28 degrees and I burn between 8 to 12 cord of ash, oak or elm each year. This unit delivers on demand.I can raise the temperature 10 degrees in 20 minutes.
