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 rotate and produce thermal energy in a process known as dielectric heating.
Major appliances, also known as white goods, comprise major household appliances and may include: air conditioners, [10] dishwashers, [10] clothes dryers, drying cabinets, freezers, refrigerators, [10] kitchen stoves, water heaters, [10] washing machines, [10] trash compactors, microwave ovens, and induction cookers.
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 ...

Gas water heaters cost between $600 and $2,700 to replace, for an average cost of about $1,650. Electric water heaters cost between $600 and $3,500 to replace, for an average cost of about $2,100 ...
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.
"Cooking meat in the microwave isn't recommended because the meat won't heat evenly, opening up the opportunity for uneven temperatures or bacteria growth," says Poon.
The copper tank contains heating elements with 7.2 kW maximum power. Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat ...
