SUMMARY
The discussion focuses on the isothermal and reversible condensation of a gas, specifically with 2 moles at a temperature of 337K and a heat of vaporization of 35.3 kJ/mol. The calculations for work (w), heat (q), internal energy (U), and enthalpy (H) reveal discrepancies, particularly with U being calculated as -76.2 kJ, while the reference book states -65 kJ. The relationship ΔH = q is confirmed for reversible processes at constant pressure, supported by thermodynamic equations involving enthalpy and internal energy.
