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.
So about how much energy does it take to raise the temperature of an average room by 10 degrees? Assuming you had a 1000 watt space heater, how long would it take?I'm wondering how to calculate the heat absorbed by the walls.ssuming the height of the room is about 10 ft tall, the total volume of the room is 10 x 300 = 3000 cu.ft. Amount of energy needed to raise temperature is given by the formula: specific heat capacity of substance x mass of substance x temperature difference.
