Let's assume that Copper has not changed its phase during this process.
we can use the heat equation,Q = mcΔT
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 66300 Jm = 0.3 gc = 390 J g⁻¹ °C⁻¹ΔT = ?
By applying the formula,
66300 J = 0.3 g x 390 J g⁻¹ °C⁻¹ x ΔT
ΔT = 566.67 °C
Hence, the temperature change of Copper during the heating process is 566.67 °C.
