Copper has the structure of a typical metal. It has a lattice of positive ions and a “sea ‘of mobile electrons.
The lattice can accommodate ions of a different metal.
Give a different use of copper that depends on each of the following.
(i) Ability of the ions in the lattice to move past each other (1m)
(ii) Presence of mobile electrons (1m)
(iii) Ability to accommodate ions of a different metal in the lattice

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.)
