Answer:
877800 Joules of energy is released
Explanation:
mass m = 3000 g
initial temperature = 80 c
Final temperature = 10 c
Change in temperature ΔT = 80 - 10 = 70 c
Heat H = ?
The relationship between these parameters is given by;
H = mcΔT
Where c = specific heat capacity = 4.18 J/gc
H = 3000 * 4.18 * 70 = 877800 Joules
