A 6.40 g sample of solid KCl was dissolved in 42.0 g of water. The initial temperature of the water was 20.60°C. After the compound dissolved, the temperature of the water was 11.30°C. Assume the heat was completely absorbed from the water and no heat was absorbed by the reaction container or the surroundings. Calculate the heat absorbed by the process. The specific heat of water is 4.184 J/g·°C.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
