After 6.00 kg of water at 71.0 °C is mixed in a perfect thermos with 3.00 kg of ice at 0.0°C, the mixture is allowed to reach equilibrium. When heat is added to or removed from a solid or liquid of mass m and specific heat capacity c, the change in entropy can be shown to be AS-mc In(T₁/T), where T, and T, are the initial and final Kelvin temperatures. Using this expression and the change in entropy for melting, find the change in entropy that occurs. Number Units J/K
