← ScienceWhich outcome arises when short-range molecular forces weaken?
A)Decreased bulk viscosity results✓
B)Increased surface tension arises
C)Solid transitions to glass
D)Crystals form readily instead
💡 Explanation
Decreased viscosity occurs because weaker molecular forces reduce the resistance to flow via decreased intermolecular friction; therefore viscosity drops, rather than surface tension increasing due to greater cohesive forces still existing.
