The microwave works as fleeting microwave radiation, usually in frequency of 2450 MHz, through food. Water, fat, and sugar molecules in food absorb energy from a microwave beam in the process named dielectric heating. It is a lot of molecules (such as that of water) are electric dipoles, meaning, that they have a positive charge in one end and a negative charge in other and consequently rotate as they try to join the variable electric field caused by a microwave beam.
This molecular movement creates a heat as rotating molecules amaze other molecules and place them in movement. Microwave heating is the most effective on liquid water, and the frozen water (where molecules are not free to rotate) is much less so on fats and sugar (at which is less molecular dipolnogo the moment), and. Microwave heating sometimes incorrectly speaks as a rotary resonance of molecules of water: such resonance only occurs in much higher frequencies, in tens gigagertsa.
Popular belief - that microwaves cook food from "inside out". Actually, microwaves are absorbed by external layers of food in a manner some similar to heat up from other methods. Beams from a microwave elektricheski operate water particles to cook food. It - actually the friction caused by movement which creates a heat and heats up food.
Wrong representation arises, because microwaves get through dry not spending substances in surfaces of many general products, and thus often bring an initial heat more deeply than other methods. Depending on water satisfy depth of initial displacement of a heat, there can be some centimetres or more with microwaves, unlike interrogation ("frying" on the American variant of English language) which is necessary on infra-red radiation, or thermal konvektsiju ovens konvektsii which bring a heat small in food surfaces. Depth of penetration of microwaves depends on food and frequency structure, with lower microwave frequencies which are a considerable quantity of penetration.
The majority of people does not think of microwave spare parts when their household goods break. They usually would receive established by the expert who will buy microwave spare parts and will make work for you, or even will buy the new. One choice which they tend to forget, they could establish it. |
