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 mol1 K1 and 31.75 J mol1 K1, 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 26.98 g mol1. (Please explain as much as possible. Why did you use the equation? Or what conditions did you see from the question? etc)
