← ScienceWhich consequence results when increased temperature fractures polymer adhesion?
A)Lowered tensile strength of the adhesive✓
B)Raised glass transition temperature reached
C)Increased van der Waals radius seen
D)Metallic bond formation in adhesive
💡 Explanation
Increased temperature causes chain mobility which activates **thermal degradation** of the adhesive polymer. Therefore, the tensile strength decreases, because chain interactions reduce, rather than other processes occurring like increased radius or metallic bond formation.
