100 Grams of Molten Lead (600°C) Is Used to Make

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.)

A) −145
B) −252
C) −302
D) −429
E) −100
