Answer:
887 J
Explanation:
the specific heat of a material is defined as the amount of heat energy required to raise the temperature of the substance by 1 K of mass 1 kg. So, the specific heat of the aluminium, c = 887 J/kg K
mass of aluminium, m = 100 g = 0.1 kg
T1 = - 9° C
T2 = 1° C
ΔT = 1 + 9 = 10° C
The amount of heat required
H = m x c x ΔT
H = 0.1 x 887 x 10 = 887 J
