1. 160 g of molten silver at its melting point, 960"C, is allowed to solidify at the same temperature and gives out 16 800 J of heat. [a] Calculate the Latent heat of silver? (b) If the specific heat capacity of silver is 230 Jkg-1K-1. how much additional heat does it give out on cooling to-40"C?Table 1 Specific Host Capacities of Common Substances Substance Specific hart capacity Substance Specific heat capacity (JNig* CH 45 x 10 2.5 x 10 35 = 10 7.1 x 10 24 x 10 2.1 x 10 13 x 10 BUThut Latent heat of fusion for gold: 1.1 x 10* J/Kq Latent heat of vaporization for gold: 6.4 x 10* J/K
