SUMMARY
The equilibrium between a liquid and its vapor at the boiling point is characterized by equal total energy (C) in both phases. The discussion clarifies that intermolecular forces (A) are significantly stronger in liquids than in gases, ruling it out. Kinetic energy (D) is not equal due to the temperature dependence of gases, leaving total energy as the correct answer. The relationship between potential energy and total energy is also explored, emphasizing the dominance of kinetic energy in gases.
