Dig into the science of how microwave ovens use electromagnetic waves to heat your food, and what you should avoid cooking in them.
--
In 1945, engineer Percy Spencer was standing near a RADAR device that produced high-intensity microwaves and noticed that his candy bar had melted. He then exposed popcorn kernels to the magnetron device, and sure enough, they popped. Soon after, the first microwave oven became available, using the very same technology. So, how does it work? Aaron Slepkov explores the science of microwave ovens.

My first experience with a microwave oven was in the early seventies. I took a job at a restaurant and someone handed me a large can of hot fudge topping and told me to put it in the microwave to heat it up before pouring it into the warmer. They failed to mention I needed to put the fudge in a bowl first so I just opened the can, put it in the microwave and turned it on. Moments later there was a lightning storm firing between the can and the walls. Interesting to watch but probably not too cool for the microwave. A second funny microwave story. My daughter, when she first moved from home, decided to make baked potatoes. She put two potatoes in the microwave and, remembering we always cooked baked potatoes for an hour, set the timer for sixty minutes. She then left to the mall. She came back an hour later to find the fire department had busted down her door and were setting up large fans to clear the dense smoke from her apartment. Lesson learned. Great video.

Some 25 years ago my Mom, a coworker of hers, and I went to a convenience store to get instant noodle soup for lunch. Back then the clerks were still managing food preparation, so this one clerk thought that the 3-minute cooking on the soup meant 9-minute cooking if she put the 3 soups together. Of course, the soups boiled out of their cups, the noodles exploded inside the microwave, and it was a mess. The clerk had to clean it up and start from scratch - without charging us double for her mistake. Lesson learned, I hope.

@michaelweaver4718 2 месяца назад

Went to an engineering school where we had to measure the size of the waves. Essentially, the size of a pencil. If you compare that to the mesh screen, even if you remove the metal between two of the holes, the wave still cannot get out. It takes a slightly larger hole, as a bit of redundancy is built in so you do not microwave your face (although your eyeballs will notice them first.)

You can put metal in a microwave. They even come with metal grates in them sometimes. Eddy current do happen, but it's generally a non issue unless you have something really conductive like aluminum, copper, or gold, and that metal is rough or crinkled. If you put a spoon in the microwave, say like you are stirring your soup and too lazy to remove it. Nothing bad will happen. You won't even get hot spots

@bushputz 2 месяца назад

I've worked in a lot of commercial kitchens. If we needed something heated quickly and didn't want to fire up a burner, we just threw it in a stainless steel 1/6 pan and nuked it. It's fine unless you leave a metal spoon in it or put a metal lid on it. Lots of people I worked with made that mistake - once.

There are two dominant heating mechanisms: dipolar rotation and ionic conduction. I have been studying the application of microwaves for assisted comminution of ores and we have demonstrated excellent results! Microwaves can selectively heat sulphide minerals in rocks and this causes differential thermal expansion between the grains and microfractures to occur in the rocks which allows for a reduction in ore competency and an increase in the liberation of valuable minerals.

@Michaelonyoutub 2 месяца назад

Microwaves heat *liquid* water, they aren't actually that great at heating frozen water, which is why frozen things often don't heat that well and heat unevenly. If something frozen is in a microwave at room temperature, parts on its surface where water might have warmed up enough to thaw due to the air around it, get cooked and then thaw the areas immediately around it allowing them to get cooked, while frozen areas surrounded by more frozen areas, remain frozen and experience no thawing/cooking. Eventually heat from areas that initially thawed and got cooked, reach the frozen areas and thaw them, but by that point the initial thawed area is likely over cooked. That why when cooking something frozen in a microwave, you should first leave it out to thaw a bit so it cooks evenly, or alternatively, find some way to warm it up above freezing with hot water or something before cooking.

@jeanmarc6517 2 месяца назад

"I dont understand, how can the sun melt this chocolate bar...but not me??" Because we transfer heat around our body and sweat to expulse heat, unlike the candy bar.

@ajchapeliere 2 месяца назад

To add a bit to the *first comment: If the waves from the magnetron in the room were primarily being focused upwards to look for aircraft, I think only a small amount would be "leaking" into the room itself, so to speak. Chocolate itself is also... Kinda wild as a material. It has a low melting point and the structures it forms when it solidifies are based on how hot it got while it was liquefied. I'm guessing the difference in composition and size might also be a factor. The human body is mostly water with some proteins for structure and from a scale perspective it's much bigger than the chocolate bar. If you want to dig a bit further into any of it, I recommend finding some videos about "specific heat" (Crash Course or one of the other STEM channels should have something). I'd also recommend videos on tempering chocolate and making ganache. Sorry if I'm coming off as ranty, I get a bit excitable when the random information in my head might have a use *and* lines up in ways I didn't expect 😂 Stay curious, my friend! *Clerical edit: some of the other comments weren't displaying when I initially said "previous"

@ajchapeliere 2 месяца назад

@@jeanmarc6517that's not very good logic. Firstly, the heat transfer from the sun comes from other parts of the electromagnetic spectrum; some frequencies of microwaves can't even get through our atmosphere because the water vapor and other molecules and particles reflect or scatter them. Secondly, sunburns are basically our skin getting cooked by the sun's UV radiation. This probably has less to do with how our bodies regulate temperature and more to do with where the microwaves were focused and the difference in water content and overall mass between the person and the chocolate bar.
