Microwave-oven-science, the microwave oven had its origins in radar research before and during world war ii. as part of this research, engineers at raytheon in the us built a large magnetron, a device that generates.... Microwaves are electromagnetic waves, radiation is how the heat in a microwave oven is transferred. the three types of heat transfer. however, it is still unclear how the heat is distributed throughout the food being subjected to the waves., microwave ovens. microwave oven drying has been accepted as a rapid alternative method to the vacuum oven method for determination of total solids in processed tomato products (chin et al., 1985), tomato pulp (wang, 1987), flour (davis and lai, 1984) and oilseeds (oomah and mazza, 1993)..

"microwave ovens cook food by generating intermolecular friction between the molecules of the food. the microwaves cause water molecules to vibrate; the increased friction between the molecules..., microwave oven. about 95 percent of american households own a microwave oven.. a microwave oven is an appliance that cooks or warms up food using microwaves produced by an electronic vacuum tube called a magnetron. the magnetron converts electricity to electromagnetic radiation (the microwaves), which is made up of waves of electric and magnetic energy. . once generated by the magnetron, the ....

A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. this induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the ..., microwave ovens were life altering from the moment they began humming and heating in homes of the 1970s. the sprinter to the conventional oven’s cross-country runner, microwaves quickened the process of cooking and reheating meals, saving time and increasing the potential for leisure over work ....

Microwaves. you may be familiar with microwave images as they are used on tv weather news and you can even use microwaves to cook your food. microwave ovens work by using microwave about 12 centimeters in length to force water and fat molecules in food to rotate., there is a chance that you will damage your microwave oven. there is a chance that you will cause a fire. there is a chance that a heated object will explode. heated water can unexpectedly burst into violent boiling..

Every microwave oven contains a magnetron, a tube in which electrons are affected by magnetic and electric fields in such a way as to produce micro wavelength radiation at about 2450 mega hertz (mhz) or 2.45 giga hertz (ghz). this microwave radiation interacts with the molecules in food.
