← ScienceWhich behavior arises when polar molecules are exposed to high-frequency oscillating electric field?
A)Dielectric heating due to molecular friction✓
B)Resonance absorption causing bond breakage
C)Photoelectric emission ionizing the molecules
D)Superconducting current within the sample
💡 Explanation
When polar molecules are exposed to a high-frequency oscillating electric field, dielectric heating occurs because the molecules attempt to align with the changing field and experience intermolecular friction, increasing the material's temperature. Therefore dielectric heating results, rather than bond breakage, emission, or superconductivity which require far different energy levels.
