Determining calories in food by burning it

** Nothing just
" BURNING SOME CALORIES "

For anyone who doesn't know, potassium chlorate react to potassium chloride and oxygen gas when heated

I took a class in college called "Energy Tech for the Future". I was advised against enrolling in the course because it was much more challenging than other courses that would fulfill my lab requirement. I have never had a more enjoyable and interesting class in my life. I learned about burning calories (the literal way, as described in this video) and many other energy-related topics. Although these topics are irrelevant to my career in music, I am so thankful that I took the course

Just so people aren't confused, this is not how calories are actually counted on your nutrition label.,
It used to be this way but it's too expensive for companies. It's an approximation based on the number of grams of certain macronutritions. For example, fat is on avg 9 calories per gram. Just add it all up, and that's how it's done for food labels.

According to Hank Green we EXPLODE it! Thank you for spreading this neat information.

When I was in high school, I actually ditched Algebra and would sneak into Chemistry class. Of course, I would get caught, but not because I was absent. The reason I got caught was I was the only one who kept submitting passing tests for the class. The principal didn't know how the handle the situation, he had never had a student leave class to go attend another class, he said he was stuck between "I want to punish you" and "I want to encourage this knowledge-seeking behavior." But in actuality, all I was really interested in was talking to the Chemistry teacher about the different kinds of acids I could use to decap integrated circuits, to which he would love to go on for hours and hours about the different kinds of solutions and how they would react, and how the silica in the chips would react once the acid worked its way through the epoxy. It was fun times. You remind me a lot of him.

The bright blue flame indicates this was a particularly sweet donut.

"How do we know how much calories in food we eat?"

"we burn them"

I've always been curious, when a nutrition label is developed for a food like a banana or avocado, do the testers include the peel of the fruit when testing it? Or would they just include what is traditionally considered edible?

[Noobixm]

This doesn’t get used often, most of the time the nutrition label people just calculate the average calories with known constants of certain ingredients in the food.

In college it was so funny telling people I was working with bombs but it was just this 😂

[kukhil_ava]

Oh yeah, we learned this in chemistry. This video helped me visualize it, thank you so much!

I used a bomb calorimeter in school for a class about thermodynamics. Which made me hate bomb calorimeters. XD
Not only is it hard to calculate time while looking at the temp, sometimes it just doesn't work.
Our last sample was a perfect little puck of benzoic acid, if I remember well. We put it exactly right in the machine, the oxygen was pumped in, we pushed the button, and after 10 minutes, the temperature had gone up by 0, 2C. Turns out our wire, which is used to start the fire, had burned. The puck was charred. It hadn't caught fire.
It's incredibly interesting. I just hate them because of the pain they caused me and my lab partner. XD

Thank you for answering the questions that I didn't I needed the answers to.

[OGO]

This was a question that lingered in my mind for a long time. Thank you for a short and nice explanation.

I have a feeling that lab smells exactly like my kitchen when I try to cook anything
