← ScienceWhich effect increases when intermolecular forces weaken within a volatile liquid solution?
A)Boiling point decreases significantly✓
B)Viscosity increases proportionally
C)Surface tension becomes consistently stronger
D)Dielectric constant rises predictably
💡 Explanation
When intermolecular forces weaken, molecules require less kinetic energy to escape the liquid phase via vaporization because the attractive forces holding them together are diminished. Therefore, boiling point decreases, rather than viscosity increasing, surface tension strengthening or dielectric constant rising which require increased cohesive energies within the solution.
