the water in the food is heated by the Micro-Waves and so heats up the food.

the "peaks" of a microwave are about the same distance apart at the hydrogen atoms in a water molecule, so just like buoys on an active water surface, they bob about as the microwaves go by. Since this means the water molecule is made to "jiggle", and motion=temperature, anything in a microwave oven that contains water will get hot!
hope that helps...

The microwave radiations induce the water molecules to vibrate thus raising their energy and thus heating up the food. This is possible because the water molecule has a permanent dipole moment.

Microwaves heat the water molecules, and the hot water molecules heat the food and container.

The microwaves actually make the food molecules vibrate. This vibration heats up the molecules and the food in turn heats up.

In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. When they excite, they move rapidly back and fourth, causing friction and eventually cooking the food. Try rubbing your hands together. Feel the heat? That's kind of how it works.

water in the food is heated by the microwaves given off by the source. they get excited and that produces heat
