  2. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

  3. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently ...

    The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...

  5. Oven - Wikipedia

    en.wikipedia.org/wiki/Oven

    An oven is a tool that is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. [1] In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. [2] Because they are used for a variety of purposes, there are ...

  6. Convection oven - Wikipedia

    en.wikipedia.org/wiki/Convection_oven

    An industrial convection oven used in the aircraft manufacturing industry. A convection oven (also known as a fan-assisted oven, turbo broiler or simply a fan oven or turbo) is an oven that has fans to circulate air around food [1] to create an evenly heated environment. In an oven without a fan natural convection circulates hot air unevenly ...

  7. Home appliance - Wikipedia

    en.wikipedia.org/wiki/Home_appliance

    Refrigerator, toaster, kettle, microwave, blender. A home appliance, also referred to as a domestic appliance, an electric appliance or a household appliance, [1] is a machine which assists in household functions [2] such as cooking, cleaning and food preservation. The domestic application attached to home appliance is tied to the definition of ...

  8. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Microwave chemistry is the science of applying microwave radiation to chemical reactions. [1][2][3][4][5] Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component ...

  9. Dielectric heating - Wikipedia

    en.wikipedia.org/wiki/Dielectric_heating

    A microwave oven uses dielectric heating to cook food. Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
