Learning Objective
I can use a model to explain how microwaves transfer energy and discuss potential safety concerns.
- 1
Microwaves heat food by making polar molecules like water vibrate, creating frictional heat.
- 2
Metals are conductors, so the electrons concentrate on the surface, leading to high voltages at sharp edges, corners, and small gaps, which can cause sparking.
- 3
Microwave radiation is not ionizing and does not alter food chemically, but transfers energy through friction.
