← ScienceWhich outcome occurs when thermal energy reduces molecular attraction within paraffin wax?
A)Viscosity decreases at melting point✓
B)Sublimation pressure remains negligible
C)Crystallinity increases significantly
D)Ionic conductivity remains constant
💡 Explanation
Reducing thermal energy reduces molecular attraction leading to decreased viscosity which changes to liquid. This phase change results from overcoming intermolecular forces, therefore liquid viscosity decreases, rather than sublimation staying, maintaining conductivity, or changing crystallinity.
