100 grams of molten lead (600Β°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21Β°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/gβ
Β°c; the latent heat of fusion and the melting point of lead are 2.45 Γ 104 j/kg and 327Β°c, respectively.)
