Molten lead of mass m = 5.0 g at a temperature t2 = 327 °C (the melting temperature of lead) was poured into a calorimeter packed with a large amount of ice at a temperature t1 = 0 °C. Find the entropy increment of the system lead-ice by the moment the thermal equilibrium is reached. The specific latent heat of melting of lead is equal to q = 22.5 J/g and its specific heat capacity is equal to c = 0.125 J/(g . K).
