Calculate the change in entropy relative to the isothermal and reversible expansion of 1 mol of a solid aluminum, from 100.0 bar to 1.0 bar, considering that the coefficient of volumetric expansion and the density of this substance respectively have the values of 69 × 10-6 K-1 and 2.702 × 103 kg m-3.
Note that: dS = Cp(dT / T) − (∂V / ∂T)pdp.

Calculate the change in entropy when one mole of metallic aluminum is heated at one bar pressure from an initial temperature of 25 °C to a final temperature of 750 °C. The molar heat capacities of solid and liquid aluminum at one bar pressure are 29.2 J mol K1 and 31.75 J mol K, respectively. The specific enthalpy of fusion of aluminum at its melting point (660.46 °C) is 396.57 J g1. The molar mass of aluminum is...
