← ScienceWhich mechanism initiates molecular bond dissociation during microwave irradiation?
A)Dielectric heating increasing thermal agitation✓
B)Compton scattering releasing energetic electrons
C)Quantum tunneling inducing proton transfer
D)Superconductivity forming Cooper pairs instabilities
💡 Explanation
Dielectric heating causes bond dissociation, because dipolar molecules align with the alternating field, increasing thermal agitation. Therefore, the bonds weaken, rather than through quantum tunneling or Compton scattering, which require much higher frequencies and molecular orientations.
