Aluminum has a specific heat capacity of 0.902 J/g °C, the amount of energy that is released when 1.0 kg of aluminum cools from 35°C to 20°C is 13,530 J.
How do we calculate the released heat?
The amount of heat that is released during any reaction will be calculated as:
Q = mcΔT, where
m = mass of aluminum = 1kg = 1000g
c = specific heat of aluminum = 0.902 J/g.°C
ΔT = change in temperature = 35 - 20 = 15 °C
On putting values we get
Q = 1000 × 0.902 × 15 = 13,530 J
Hence released heat is 13,530 J.
