Lead glass contains 18-40% by mass of pbo (instead of cao in regular glass). lead glass is still used industrially, but lead crystal drinking goblets are no longer considered safe, as the lead may leach out and cause toxic responses in humans. a particular 286-g lead crystal goblet that holds 550 ml of liquid is 19 % pbo by mass, and it leaches 4.2 micrograms of lead every time it is filled.

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.)
