Having studied mixtures at school, Daniel wanted to investigate how to separate the parts from different mixtures. He knew that the individual components of a solution kept their properties. So, Daniel gathered his materials and began to separate some of the mixture combinations. Which of the following tests could he perform to separate different kinds of mixtures? Choose the three statements that apply. A. Use a cup of salt and dissolve it by adding water. B. Use a magnet to separate the metal parts. C. Use a hotplate to evaporate the liquid. D. Use a filter to separate large particles.

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.)
