How does food get heated up in a microwave oven? Microwaves, produced by the magnetron in the microwave oven, are absorbed by some of the chemicals in foods—mostly water molecules. As the water molecules rotate under the influence of the applied electric field, they bump into other molecules surrounding them and transfer some of their kinetic energy. By the Kinetic Particle Theory, as the particles in the food get more kinetic energy, the food gets heated up. This class will also explore the effect of constructive/destructive interference, rotation of molecule and effect of metal on microwave heating.
