Compressing a gas in a fire piston 

On a sad and sick note that is what happened to the people inside the Titan sub when it imploded. The pressure when from just 14.7 PSI to 6000 psi in a millisecond. Not only were they turned to paste but they were incinerated. Well at least it happened so fast they never knew what killed this. May they rest in peace.

If you close your eyes, you can hear Harry Potter

Amazing demonstration!

Genius sir I also came here while studying the kinetic theory of gases cause it is kinda amazing to look into..❤️really appreciating the job..

"Hey man, got a light?"

Whoa. Nice video out there. Pretty nice. Thanks for sharing.

I'm amazed to see a fire piston video with NO diesel engine comments devolving into hate and discontent 😆 Rudolph Diesel got the idea for his engine from a fire piston which was common for fire starting at the time.

Thanks for the video ! I'd saw beargrills starting fire with this technique during one of hos episode !

Very informative. Thanks

good explanation of titan/s final milliseconds

Thank you very much...yo video rlly helpd

Wow, that's so pog! Thanks for the informative video.

Thank you sir😊

The naturally always vibrating and wiggling particles get trapped together closer and closer as the piston is pushed downward. As the space is decreased as the piston moves down, the vibrating particles start bumping into each other, and moving faster and faster, this creates heat. If the plunger is pushed down fast enough, the heat gets concentrated into the tiny area and get hot enough to ignite the cotton. As said in the video if the plunger is pushed down too slowly, the same heat is still created, but it is allowed to warm up the glass walls of the cylinder, it dissipates, and it won't be as hot and concentrated when the piston gets to the bottom.

Like the video. Good job. Only thing I would change is @1:46 I would change “microscopic” to “molecular”. For the same reason why I think it is funny watching news stories about Covid 19 with stock footage of “scientists” looking at viruses with a compound light microscope. It is possible to see viruses with such a device but not really the tool for the job.

I do not believe that most of the energy comes from the piston. It’s an adiabatic process. You are taking the kinetic energy from a large volume of gas and reducing the volume. The energy remains constant, but since the volume is lower the temperature jumps higher. At least, that’s how I remember it. I may remember wrong.

WOOOOOOOOOOOOOOOOOOOOOOOOOOOW. Thank you

its better than rubbing two sticks together. and it looks fun

This is what happened to the crew on the Titan sub except instead of 15:1 compression ratio it was more like 300:1.

I'm curious if there's a minimum amount of space required to generate enough energy to cause ignition

2023 June: This is what happened to the Titian sub crew at the depth of 4000m when the implosion occurred. Human fats is equivalent to the cotton fire in this demonstration.

This is essentially what happened to the Ocean Gate Titan submarine. Anything (anyone) organic in the sub was turned to ash and compressed CO2 in a fraction of a second. RIP

i wonder if you could toast small pieces of bread this way.

I came here to find out how diesel engines work. Unlike a regular car they do not use spark plugs. They just compress and ignite the fuel air mixture. This explains how

Maybe the Titan passengers turned into diamonds.

got it

Ur students must be lucky

what happens if you push the piston down and hold it there without release back up? Will it lead to an explosion of the piston?

Is there metal to metal contact? I can hear the piston hitting the bottom.

I kept it at PV= NRT , so as P and V changed, so did T.

the origin of diesel engine

Soak the cotton with a bit of diesel

Gobek api aka fire piston..malay ancient technology

And that folks is how a diesel engine works...

The ignition temperature of cotton is about 400 degrees C:P

Its how diesel engines work by compression ignition.

Can someone calculate how much heat was created during one movement of the piston?

Basically a diesel engine.

I’ve had trapped air before…

This is how a car piston works, so could we run a car on just air compression.

this is how diesel engine works

How diesel engines work

Just to let you know, this video is being used by climate "skeptics" to suggest that atmospheric pressure is responsible for earth's surface temperature rather than the greenhouse effect. I wonder if you might comment on this for people's edification. Thx!

The explanation is FALSE. Compression should NOT increase temperature, only pressure. A simple lab experiment would bare this out. You ARE doing work, but you are not directly raising the temperature of the gas, the combustion certainly raises the temperature of the gas, but the applied pressure does not. I seem to remember the explanation of fire as a chemical reaction involving oxygen called oxidation. The increased pressure causes the collisions which causes the reaction (rearrangement of the molecules) which releases the heat to create lower energy molecules. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eocyl9dZ7W0.html . This is the same false explanation used to explain diesel engines on wikipedia and other places but it clearly violates the laws of physics. Institute of Physics? Edit: the linked video claims that the heat we feel from fire is due to the kinetic energy of speeding molecules/particles hitting our skin, which is obviously false. Think of a lantern.
