← ScienceWhich effect results when increasing intermolecular distance in a gas?
A)Van der Waals forces decrease✓
B)Kinetic energy increases sharply
C)Molecular attraction dominates repulsions
D)Adiabatic compression induces liquefaction
💡 Explanation
Van der Waals forces are distance-dependent; increasing distance weakens the dipole interactions through dispersion. Hence, Van der Waals forces decrease because the attractive forces rapidly diminish with increased separation; therefore, the attraction lessens, rather than strengthening repulsion, influencing energy or state.
