27. (6 points) Calculate the energy in the form of heat (in kJ) required to change 71.8 g of liquid water at 25.7 °C to ice at 16.1 °C. Assume that no energy in the form of heat is transferred to the environment. (Heat of fusion = 333 J/g; heat of vaporization=2256 J/g; specific heat capacities: ice = 2.06 J/g-K, liquid water-4.184 J/g.K) 25.7°C) + (-14.12() = 9.6°C (4.184 J/g. K) ~ 2006 X 7.187 £/.2575/9-k/ 9.6. -T4 28. (6 points) If 46.1 g Cu at 11.6 °C is placed in 85.0 g H₂0 at 72.4 °C, what is the final temperature of the mixture? The specific heat capacities of copper and water are 0.385 J/g-K and 4.184 J/g-K, respectively. (46.15) (166) 135.0) (723) A 74=324,
