Elementary Productions: Properties of Liquid Nitrogen

[knutkleven]

how did you get liquid nitrogen in NORWAY!?!

[SirSmokeal0t]

>tasteless fluid

How the fuck did they test this? Don't tell me some guy once said "Well, we ain't gonna find out until we try" and drank it.

[Chiefhalo19]

omg, i was seriously about to ask that, then i saw your comment!

[ganush1987]

i believe they know its tasteless due to 78% of the earths atmosphere being composed of nitrogen

[kewlfilez]

@SirSmokeal0t Search "darwinawards nitrogen" (without the quotes) and you'll find out.

[SiliciumScience]

you have liquid nitrogen at home? omg the two-wall termojar cost 500€ X-/

[hyunchoi98]

you should light the solid butane

[liquidgrain]

Solid butane cant combust because the butane itself is not burning, the vapors are. And during the solid phase there is no vapour prioduced due to its phase- I'm only 14 and I know that, you should know too >:-(

[hyunchoi98]

well i'm 11.

[lithiumw]

It wouldn't burn. The flash point of butane is -60°C.

Question:

Where did you get liquid Nitrogen?

You didn't buy it in a shop, did you?

[twirlywirly55]

I u have a lot of money you can get liquid nitrogen generators about the size of a small fridge with a tank in side and compressor to .

[werewolf7789]

do u now those air duster cans for electronics if flip them upside down and spray it liquid nitrogen comes out

[mabakken]

Actually, fluorocarbons are used for that purpose, because they are much more easily compressed into a gas. No can would be able to keep liquid Nitrogen in a container, because the pressure is way too high.

[MysticVulture]

The "liquid nitrogen" that comes out is actually difluoroethane, also a cryogenic liquid. If you put liquid nitrogen in a metal can, it would implode due to Charles's law; the temperature in Kelvins is determined by the increase or decrease in atmospheric pressure.

[mabakken]

Difluoroethane is neither used in air dusters, nor is it a cryogenic liquid (= < -150 degrees C). If you put liquid Nitrogen in a metal can, the metal can will quickly explode as the Nitrogen boils away. The temperature- decrease is not enough to cause the can to implode. This is due to several things, such as the Leidenfrost effect and because the liquid Nitrogen boils very fast.

ive been trying to obtain some liquid n for a while its cheap but hard to find

[TAz69x]

It's rare that you find someone that not only has excellent chemistry knowledge (and high intelligence), but is also talented at video production, has the time/courtesy to help (and inform) others and post such great videos, and is so courteous, great, and helpful as well!

Great job!, mabakken

Keep the great videos coming! (I myself am looking at how to produce Propionyl Chloride, and then to watch it hydrolyze in water afterwards!)

^^

[mabakken]

Wow, that is a lot of compliments!

You have no idea how much I appreciate the positive feedback!

Although I have moved away from home, I have some ideas for some new videos! They will be made and posted during the summer of 2009 =)

Again...thank you!!! =) And good luck with your synthesis!

[MysticVulture]

In plain English, you can get liquid nitrogen from a gas station.

[LookItsRiceCake]

Uh, tasteless?

Lol.

I wonder who gets to test that.

[mabakken]

The atmosphere you're breathing is 78% Nitrogen!

Can you taste anything? :P

[LookItsRiceCake]

(Chuckles) No, just seeing "liquid nitrogen is tasteless" drew up a real bizarre mental image.

[MysticVulture]

At 2:28 the deflated balloon looks like a human stomach!

[thedude77777]

and u would know how those look like?

[b43e65f77]

I love the butane cloud

[mabakken]

It is available from chemical suppliers, but a "different" type of chemicals: gases! Try your nearest gas- supplier. If they don't have it, they should know someone who does.

[ThatBum5]

"Liquid Nitrogen is a colorless, orderless, and tasteless fluid."

Tasteless? Why would anyone want to taste liquid nitrogen? How do you know it doesn't taste like anything? The alleged person who tasted it must have had their tongue shattered.

That just struck me as very funny.

Anyway, great demonstration.

[mabakken]

hehe...I knew I would get that question: You breathe Nitrogen don't you? It's tasteless, isn't it? The same goes for liquid Nitrogen. One can put it in your mouth (I did), and because of the Leidenfrost effect (as demonstrated in the video), you don't get burnt by the extreme cold. Don't swallow it, though! :P

[ThatBum5]

Ah, it's kinda like if you put dry ice in your mouth and you keep moving it around so you don't get frostbit, it doesn't taste like anything. Then you can infer that the gas form doesn't taste like anything either.

Makes sense. I feel kinda stupid now.

Anyway, could you do another video of putting more random stuff in liquid nitrogen? I want to see a rubber bounce ball explode, I saw that in an Internet facts list once, but never a video or even pictures.

Godspeed, and don't blow yourself up.

[mabakken]

Don't ever feel stupid for making wrong assumptions!! Where would science be today if assumptions were to be stupidified? =)

Unfortunately I don't have a rubber ball, but I will soon post a video where I flash- freeze Nitrogen Dioxide gas.

[frizspin175]

my science teacher dunked a rubber ball in liquid nitrogen and then threw it into a metal door in the school and dented it!

[mabakken]

hehe...it happens :P

[derkozten]

hahaha, there it is... the corageous fearless experimenters Science needs XD

Just like me when touching mineral acids

[Basco36]

great nitrogen videos.
