← ScienceWhich outcome would arise if van der Waals forces weakened in polyethylene?
A)Reduced tensile strength occurs then✓
B)Increased hardness comes to play
C)Higher melting point ensues fast
D)Enhanced chemical resistance evolves often
💡 Explanation
Reduced tensile strength arises because weaker intermolecular forces allows polymer chains to slide more easily, reducing the plastics resistance to deformation via chain slippage; therefore the plastic deforms more easily, rather than resists forces through crosslinking under significant forces.
