Answer:
The mass of the aluminium is 293.4 g
Explanation:
The question requires us to know the specific heat capacity of aluminium which is 897 J/(kg·°C)
Hence we have the heat gain formula given by the following relation;
ΔH = mass, m × specific heat capacity, c × change in temperature, Δt
Hence ΔH = m×c×Δt
Where:
ΔH = The heat supplied to raise the temperature of the aluminium = 6290 J
m = Required mass
Δt = Temperature change = 23.9 °C
c = Specific heat capacity of aluminium = 897 J/(kg·°C)
Plugging in the values gives;
6290 = m × 897 × 23.9
∴ m = 6290/(897×23.9) = 0.2934 kg = 293.4 g
The mass of the aluminium = 293.4 g.
