Answer:
69.60 °C
Explanation:
Q = cmΔT..................... Equation 1
Where Q = Quantity of heat added to the gold, c = specific heat capacity of the gold, m = mass of the gold, ΔT = temperature change.
Making ΔT the subject of the equation,
ΔT = Q/cm ...................... Equation 2
Given: Q = 98 J, c = 0.128 J/g.°C, m = 11 g.
Substituting into equation 2
ΔT = 98/(0.128×11)
ΔT = 98/1.408
ΔT = 69.60 °C
Hence the temperature change = 69.60 °C
