No matter the field of work, technology has taken over its command and has led to the upbringing of several conventional methods of completing the tasks. Not only has technological advancements helped in making the work of mankind easier than before, but it has also resulted in the development of society as a whole.
Well, one such great discovery that has helped humans over time is the microwave. The study that microwave signals can be brought into use for generating thermal energy has been of great assistance in accomplishing several tasks both at household and commercial levels. Nowadays, it is hardly possible that a house does not have a microwave in it.
Nevertheless, using a microwave is easy, simple, and convenient, but understanding the principle on which it operates and performs its functioning is even easier. Herein, we are going to learn about the principle of microwave heating and the benefits that you get to acknowledge once you start using a microwave.
Why microwaving your urine is a bad idea?
Many people failed drug tests because they failed to maintain the synthetic urine temperature. The problem with the microwave keeping the pee sample warm is that it can overheat the urine sample, making it too hot for the drug test. Hence you should avoid microwaving urine for the drug test. The urinator urine heating system is better than microwave heating. You should avoid using hand warmers and heat packets for the test.
What Is The Principle Of Microwave Heating?
Microwave ovens operate on the basic principle of converting electromagnetic energy into heat(thermal) energy. The microwaves radiate electromagnetic energy. It is further transformed into thermal energy, which is how a microwave works.
In a microwave oven, the two fields, the electrical field and the magnetic field, oscillate 90 degrees to each other and pass out radiations. Whenever a molecule having an opposite charge comes into the range of these radiations, it moves in such a way to get aligned with them. This results in a loss of energy from the dipole due to collision and molecular friction.
As a result, heat is transmitted out. Similarly, the phenomenon of the microwave by which it heats the food taken out directly from the refrigerator works in the same manner. The water molecules of the food are converted into heat, thereby heating the food overall.
Microwaves are equipped with enough frequency and space that they can penetrate deep inside the food and heat it properly and especially in the least time involved. Microwaves work only with polar liquids such as water. They show no effect on liquids that are nonpolar.
Advantages of Using a Microwave
No doubt every invention that has been done in the past is helpful in some way or the other. The discovery of microwave radiation to generate a thermal effect has been a significant revolution. There are some advantages associated with using the microwave. They are-
•Microwaves are a quick and convenient way of heating the leftover food in no time, which is too different from the conventional techniques. Usually, when you are in a hurry to leave for work, microwaves can become a great savior so that you do not have to miss your breakfast.
•One good advantage of heating food in a microwave oven over any other source is that microwave ovens are only reactive to polar compounds, that is, water. It clearly signifies that microwave heating will not affect the nutritional value of the nonpolar compounds.
Disadvantages of Using a Microwave
Apart from the advantages discussed above, the use of microwaves counts for some serious disadvantages as well. At times, these disadvantages can be truly hazardous. Below mentioned are some of the crucial disadvantages of bringing a microwave into use. They are-
•While using a microwave oven, you have to be extremely careful of the fact that you only heat the food in specific utensils that are fine to be kept in the microwave oven, that is, the microwave utensils. If not, other utensils can result in a chemical reaction between the food and the vessel. It might destroy the food and also have a severe effect on your health.
•The heat radiations emitting out of the microwave impact the body too. One needs to be careful in using the microwave. Otherwise, it might also cause burns. Excessive exposure to heat can sometimes result in having a burning sensation in your eyes.
Microwaves have been an amazing discovery, and ever since they were brought into the market, they have undoubtedly proven to be efficient. It can not be forgotten that apart from multiple advantages, microwaves showcase some major disadvantages while in use. And one must be aware of both the pros and cons of using a microwave.
Most importantly, the heating effect of the microwaves can have a severe impact on your food. The necessary nutrients of the food might get destroyed due to excessive heat that is radiated by the microwave onto your food. Uncontrollable use of microwaves can result in you getting health problems and even cancer.
Therefore, it should be kept in mind that although the microwave is beneficial and valuable in today’s fast-growing and rapidly changing world, one must be extremely careful in how they bring the microwave into use. Also, try to be less dependent on Microwave for your routine work.
