← ScienceWhich mechanism explains microwave heating when food is exposed to electromagnetic fields?
A)Dielectric polarization induces molecular rotation✓
B)Convection distributes heat across food volume
C)Radiation directly transfers energy to surface
D)Conduction heats food via pan contact
💡 Explanation
When food is exposed to microwave fields, dielectric polarization occurs because polar molecules align with the oscillating electric field, causing them to rotate and generate heat through friction. Therefore molecular rotation results, rather than convection, radiation or conduction which operate via different heat transfer mechanism.
