Microwave Ovens

A microwave oven uses electricity to excite the water molecules within food. As the water molecules move around, heat is transferred into the food. This type of heat transfer is more efficient than the heat transfer that occurs inside of an oven or on the stovetop. Microwave ovens are available in a wide range of sizes. Many models feature turntables that rotate the food for even heating. Convenience features include one-touch cooking for common foods like popcorn or baked potatoes. The power of a microwave oven is rated in watts, with most appliances offering 700 to 1500 watts of power.
