When benzene freezes at 1 atm and at 5.5°c its mass density changes from 0.879 g·cm−3 to 0.891 g·cm−3. the enthalpy of fusion is 10.59 kj·mol−1. estimate the freezing point of benzene at 1,145 atm.

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.)
