Question
**Thermodynamics of Aluminum** When the temperature of aluminum is increased from 600°C to 700°C, the change in molar entropy is noted as 15 J K⁻¹ mol⁻¹. Aluminum transitions from solid to liquid at its melting point of 660°C. During this phase transition, the heat capacities for the liquid and solid states of aluminum are 34 J K⁻¹ mol⁻¹ and 32 J K⁻¹ mol⁻¹, respectively. Questions for Analysis: (a) Determine the heat of fusion for aluminum. (b) Calculate the change in molar enthalpy as aluminum's temperature increases from 600°C to 700°C.
