According to q formula: q = M C ΔT when q is the energy required in Joule M is the mass per kilogram=5.63 g /1000 = 0.00563 Kg C is the specific heat capacity of the gold J(Kg-K) = 125.6 J(Kg-K)(should be given in the specific heat capacity table) ΔT is the change in the temperature = (32 - 21) = 11 C° ∴q = 0.00563 * 125.6 * 11 = 7.78 J = 1.86 Cal
