Burning 7 Calories in Liquid Oxygen

7 Calories doesn't seem like that much energy - until you burn them in liquid oxygen. Now it finally makes sense why it takes so much exercise to burn calories.

I was hoping for a numerical figure and what I got was "a lot".

10/10 would watch again.

That’s a good test tube. Extreme cold to extreme hot in a matter of seconds

7 calories is the average energy your body will get by digesting that chip. The actual energy stored in the bonds between the atoms is obviously much, much higher.

[Tiago]

7 calories, also known as 7 kilo calories.

[batkata]

The moral of the story: never drink liquid oxygen with your dinner!

[ariesword]

For those wondering 7 Cal. is 7000 calories. He's using the American Food Calories which is a kilo calorie in most other countries.

Also, calories are a measurement of energy.

"Mona's Hot Mom" caught me off-guard 👀

So many people think oxygen is flammable but it's not. It just makes any flammable material much much much more flammable.

If you think about it, 7 kcal is the heat that you can give to a kilo of water to rise it's temperature 7 degrees Celsius. And knowing how difficult it is to rise water's temperature, it is A LOT. Just a reminder of how complex our reactions really are 😊

[CosmicWaltz]

In a chemical sense, you mean 7000 calories, yeah? The food we eat is measured in kilo calories, and we just drop the "kilo" part. So, 7 Calories on the nutrition information is 7000 actual calories.

No one gonna ask eho Mona's Hot Mom is? I see them as an absolute W

[WhatNameShouldiType]

It’s important to note that this is 7 Calories (kcal), not 7 calories.

Calories = food calories, which is 1000x of regular calories

[jacobtinkle]

Fun fact: they actually explode food in a bomb calorimeter to find out how much calories it has

[BenjaminSteber]

Please keep in mind that the term "Calorie" is colloquial. It's the commonly accepted abbreviation for "Kilocalorie" in other words, that seven calorie chip is technically seven thousand calories.

[THarSul]

this was cool, but you should do an actual caloric capacity experiment.

[miner_sd]

fun fact: you can cut steel with an oxygen/pasta fueled thermal lance

[Boxersteavee]

*starship burns methalox, which is a mixture of liquid oxygen and liquid methane. It's not just any old "natural gas", and it's certainly not gaseous

For those who are still wondering the unit for energy in food is the Calorie.

IIRC, a Calorie is defined as:

"How much energy is required to heat a 1 cm cube of space to 1 degree C° at sea level."

The experiment works like this:

You have a container, (Con A). And you place Con A in a chamer that mimics atmospheric pressure at sea level. Within Con A is a 1 cm^3 cube (this notation is the same as writing out 1cm by 1cm by 1cm). The cube has a given about of food stuf (rice, chips, whatever is being tested for caloric value.)

[ I forgot to mention that there is water within Con A abd that the Cube stants above the water on a pillar that will ignite and heat the food item. ]


After the food item is ignited abd subsequently burned, you then messure the time it takes for the heat from that food item to raise the water within Con A to 1 degree C° above its current temp and there you have a Calorie.


Now I must express that this is going off my memory and not from google, so im sure im misremembering somethings or mixing the order of operations.

[TheyTookStrawb]

that little chip gives you energy for .07 miles.

Important to note that to obtain the energy of food, the body needs to spend energy in digestion, movement of the molecules and even to start the bioreactions, which makes this experiment an overestimation. That said, these kind of fatty and sugary foods are really easy to digest so they are usually less healthy than the same calories in other forms like idk, vegetables.
