The temperature change is 96.9 °C
Using Q = mcΔT where Q = quantity of energy applied = 250 J, m = mass of gold = 20 g, c = specific heat capacity of gold = 0.129 J/g °C and ΔT = temperature change
Since we require the temperature change, making ΔT subject of the formula, we have
ΔT = Q/mc
substituting the values of the variables into the equation, we have
ΔT = 250 J/(20 g × 0.129 J/g °C)
ΔT = 250 J/(2.58 J/°C)
ΔT = 96.89 °C
ΔT ≅ 96.9 °C
So, the temperature change is 96.9 °C
