← ScienceWhich phenomenon enables microwave energy delivery to food?
A)Dielectric heating via molecular rotation✓
B)Convective currents inducing surface burning
C)Radiant infrared propagation absorption efficiency
D)Metallic waveguide induced ohmic resistance
💡 Explanation
Microwaves excite water molecules, then dielectric heating occurs due to molecular rotation, raising the food temperature volumetrically rather than superficially. This efficient energy transfer throughout the food occurs because dipole alignment losses dominate, therefore A is correct rather than B, C, or D since those pertain to alternative dissimilar thermal mechanisms
