nice bald spot.

[TheAna101]

Yeah, so much easier and funner to learn when you get demonstrations. We do the most stupidist and boringist labs ever.

[Staceyj82]

I am a science teacher, where can I get liquid nitrogen for demonstrations like this?

[kb1leog]

Perfect example of the law.

[schoolboi180]

excuse me i would like to use this video as a project. (i will give u credit)

[Mauroo13]

subbed :)

[respitado09]

very good

[Ogaitnas900]

Note to self: tie balloons before class :p awesome videos

[EminetCarnage2]

that... is.... BADASS!

[schoolbadman]

Teachers like this man can actually make school worthwhile!!!

[Random0Raider]

Maybe that works as well. The rule i quoted is correct however. But perhaps The 2 laws are related.

[jordanritch]

Hey I really enjoy your videos you look like you really enjoy your job! please post more!!!!

[StevenRNicholls]

Professor, if liquid nitrogen is capable of freezing things instantly and causing the oxygen to condense, how is it that you can touch it with your bare hands immediately after pouring it onto the glove? It couldn't have warmed that fast, could it? (I am not a Chemistry or Science major).

I'll see if my Professor can incorporate liquid nitrogen into our Poli Sci lectures. Maybe during a bit on Russia :P

[robertburkottawa]

Liquid nitrogen, although very cold, is at its boiling point. Thus it takes very little heat to evaporate it. Small amounts on your hand will not do any damage because the droplets instantly evaporate.

[djohns71095]

@StevenRNicholls(in regards to the professor's rebuttal), that's why you sir, are not a science major; and are wasting your invaluable time and money on an education that's meant for spoiled pot heads.

@robertburkottawa leidenfrost effect

[jityr2]

@robertburkottawa If it takes very little heat to vaporize it, how does it stay in it's liquid state so easily while in the bottle?

[bonham1981]

@StevenRNicholls

Imagine water droplets on a hot oven plate. They float on a cushion of water vapor. You can handle liquid nitrogen quite safely without gloves, it's even safer considering some could get into your glove, which may cause burns. I sometimes had small 1st degree burns on the back of my fingers, because the nitrogen stuck to the hair and effected a small area for a little too long.

@StevenRNicholls

You can touch it briefly thanks to the leidenfrost effect.

Google it

[dexterdude87]

whats the difference between Charles Law and Bernoulli's principle?

[mikemillenium17]

Charles's Law deals with the temperature and volume of gases. Bernoulli's Principle deals with the velocity and pressure of fluids. They're unrelated.

[felined21]

wow thank you very much! yes, i wish there were more teachers like him

[Charles2337]

Awesome.

[Random0Raider]

PV=nRT (the ideal gas equation), is this that, but in a simpler form?

great teacher, wish we used liquid nitrogen more. haha

[mikemillenium17]

The ideal gas equation combines several gas laws, namely Charles's Law, Boyle's Law, and Avogadro's Law.

Saluts from ROMANIA !

Y'm a student in the first year at the Department of Aplied Chemistry and Science of Material from Polytehnic University Bucharest. Very wonderful course you teach, i wish that my teachers hold courses in this way, that make boardom matter extraordinary interesting, and very easy to understand. With the hope that in future i will participate at one of your course, I say to you good luck, and keep posting this kind of clips.

Are a lot of romanian chemist in Canada,..

[MonkeyScout]

Keep making videos, these are great

[bullhead2012]

Great teacher but that was an expensive experiment with the use of liquid nitrogen. He could have done that with hot and cold water but the volume change wouldn't have been as profound.

[BMayhew60]

I've used liquid nitrogen a lot and it really isn't very expensive. There might be $0.50, if that worth in that dewer (that's what it's called) he has. Some cryogenic liquids are expensive, but liquid nitrogen can be purchased in huge vessels for cheap. Most labs and particularly at a University have it around anyway for other purposes.

[fadel2000]

maan i wish i had this guy as my teacher ! my teacher sucks hate you bastard!

[chemistmertcanozel]

wonderful teacherrr

[JandOlive]

great clips, what a good teacher.

thanks loads
