Answer:
Q = mass x sph x temp change
temp change = Q/(mass x sph)
Temp change =57/(22 x .903)
Temp Change = 2.97 ∘C
Temp change 3.0 ∘C
or
We can use the heat equation,
Q = mcΔT
Where Q is the amount of energy transferred (J), m is the mass of the substance (g), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
The given data
Q = 52 J
m = 28.4 g
c = 0.903 J g⁻¹ °C⁻¹
ΔT = ?
By applying the formula,
52 J = 28.4 g x 0.903 J g⁻¹ °C⁻¹ x ΔT
ΔT = 2.03 °C
Hence, the temperature change of aluminium during the heating process is 2.03 °C.
