Work in the oil industry, the thick oil is the biggest pain in the ass to work with. Near impossible to pump, very very sticky...just terribly annoying to deal with.

@hackum1 14 лет назад

The professor seems like the kindest and most patient and benevolent person on the planet.

Oh.. another happy day for neil...

@MrMikemcmike 11 лет назад

I'm from Canada (Alberta, where the oil comes from :P) and we honestly didn't learn anything about oil or oil spills until high school, You'd think it'd be more important in our curriculum but we never learned about it till grade 12 chemistry when you learn about fractional distilling and organic chemistry. Like you I really wish we'd done this experiment in elementary.

@GetMeThere1 14 лет назад

Excellent video! I liked the oil spill demo. It was also rather fun to discover that The Professor seems quite drawn to thick crude oil on a stick :D

@4:24 Now, if you mixed a little flour, some sugar and an egg...

@TSorovanMHael 13 лет назад

I live in Utah in the US. A lot of the Crude produced here come out of the ground very warm, about 80-90 degrees C. Once you cool it down to room temp. a lot of it turns into solid wax.

@Lavabug 14 лет назад

Periodic videos needs to make a video on graphite! Lots of interesting properties to discuss.

@Jullebrus 12 лет назад

On the school I work for now we have crude oil from the north sea. One of the experiments we run frequently is distillation of the oil. Last time I had the demonstration the beaker broke from the heat and filled the room with smoke. Oh well, at least we practiced some health, environment and safety :P

@jb082598 10 лет назад

Thanks for the sympathy

@ijunkie 11 лет назад

Thanks for the concerns prof. There was recently a new slick discovered near the spill site; minor, but still a reminder of how dangerous these wells are in the gulf. By the way, I can report a similar experience in American high school. There was very little lab in chemistry. Funding issue? I don't know. It was mostly theory I have forgotten now. These videos have given me curiosity I think, that which Einstein once said is so easily "crushed" by "society."

@rushianokun 13 лет назад

THis is how the incident should have been explained, scientifically, after viewing such an empirical and clear demonstration there is little room for biased conjetures or any other political mischief. Im in love with this videos. Thank you, wholeheartedly.

@dougla2345 11 лет назад

Yes professor there is a lake called the "Pitch Lake" quite straight to the point really. Its in La Brea that is southern Trinidad and its "really quite interesting" :D. I know this because I was born and and still live here in Trinidad. During the rainy season, when pools of water collect on the pitch it makes the water very warm during mid day and come pools can be 3-5 feet deep thus making a number of natural Jacuzzi if you will. It really is "quite nice" the tourist love it. :D cheers

@cwbh10 14 лет назад

That last message was very nice. Thank you!

@lmcmullen3 11 лет назад

love these vids... and the profs are hilarious...

@xaiber1 14 лет назад

I'm actually from Trinidad an there is a Lake where it bubbles up which we call locally the "Pitch Lake" . It has also become quite the tourist attractions to those who know about it.

@eljohn3 11 лет назад

A gentleman and his wife walked through the airport with a what looked like a bottle of maple syrup... turns out, it was a bottle of crude oil from his personal oil well down in Texas. It looked remarkably similar to the oil he shows from GB.

@paulallen5576 12 лет назад

Yes that's right, we chemists want all the oil to ourselves for all the reactions that we love to do. Petrochemists actually have one of the lower end salaries in the oil industry as it's a pretty mature research sector, so a clever chemist would look elsewhere to make lots of money.

@Sentinalh 11 лет назад

You're from Canada? Excellent. I've been wanting to ask a Canadian what they think about the Canadian Tar Sands extraction and the ecological impact of it.

@RahilSethi 8 лет назад

That viscous crude oil wasn't a crude oil, but marmite :-P

@PaulusTheMisionary 14 лет назад

I been to the "pitch lake" in trinidad. It truly is a remarkable phenomenon.

@judymaehs 14 лет назад

Yes Professor, we do have a pitch lake in Trinidad. Folk come from all over the world to view it. It bubbles up with the thick black gooey stuff which eventually hardens into pitch.

@kingzing12 13 лет назад

sam did that experiment when i was in year5 and that was last year

@maekern 14 лет назад

You fine folks have been going beyond your original mission of providing abstract educational information (wonderful and important though that is) and are now providing a real public service in the form of scientific background information on important issues of the day. "Proper" news sources aren't doing nearly as good a job as you are. Thank you. Keep it up!

@1983CHEVYSUBURBAN 11 лет назад

i would like to say how much i enjoy your videos if i had seen some of the things you show there is no doubt i would have pursued a career in science. I had believed i wouldn't use chemistry in the automotive field. haha internal combustion engines are full of chemistry from the cooling system to the fuel to the lubrication system. thank you and i look forward to more videos

@rageagainstthebath 14 лет назад

@okuma0kuma I like the huge roller idea. Simply covered with a thick cloth, collecting water and oil mixture. When the tank fills up, you might pump out the collecter water back to the sea, since water and oil don't really mix well. And, with custom-built engine it probably could run on collected oil. Perfect idea!

@np231 14 лет назад

great video and message..

@98JMA 12 лет назад

Gold is an element, therefore it is also a chemical. The same applies for any single other possible tangible object, including the Bose-Einstein condensate you mention.

@BENBOBBY 14 лет назад

I really like this video series and the professor is excellent at explaining concepts but always leaves me wanting to know more about the science behind it all! Whereas the experiment was needlessly long winded and didnt really have any conclusion. Questions like "why is it black" and "can you drink heavy water" etc are more interesting. Some diagrams would be good to help visualise some things though such as when you mention rings of benzene. Keep up the good work. :D

@Justinofalltrades1 14 лет назад

with the thick and thin crude oil, does one yield more useable product than the other?

@xxXpitboyXxx 12 лет назад

well some schools are certainly different from others. lucky for me, i went to a higher elementary school. so i had lots of experiments dealing with things like conducting electricity in electric magnets and heat conducting metals vs other metals and materials. also refraction and reflection in middle school and all kinds of stuff. but with lots of cool and educational experiments, comes much expense when it comes to money and materials. i think experiments are far underrated. GO science!!

@Satprag 14 лет назад

Thank you, sir! you always give a interesting and LUCID explanation. Luv ur videos. You have hairs of Einstien and the brain and good thng u dont have that moustache.

@kowalityjesus 11 лет назад

in 8th grade, Mr Weir drank a sip of crude oil, to everyone's disgust and subsequently to his delight. He also brought in a guinea worm which was actually cooked spaghetti, to a similar effect.

@eyreland 14 лет назад

@Stormrunner0002 For engines made after 1960, Desil or Gas -- this "refined crude" point is true. I don't know to what extent it applies to petrol based Marine Boilers, but most post 1970 marine boilers probably prefer refined products.

@JB000001 14 лет назад

Leave the oil on the surface where it can be "scooped" up. The oil and water collected afterwards can be separated again using a centrifuge.

@vlasktom 11 лет назад

Chemistry question. Carbon Dioxide is CO2, right? The air we breath is O2, right? Is there not a way to take in CO2, break the Carbon and Oxygen bond, and be left with pure Carbon and atmospheric Oxygen?

@Hlaford347 14 лет назад

I have family down in Mobile, right on the gulf coast. It's a horrible area right now :(

@EssJay00 14 лет назад

@Rib640 Absolutley right, I was more alluding to the way we have grown accustomed to having this resource and how in turn it has affected us and generally as a whole won't consider trying to improve the current model until we are completely dry and have nothing left for regular people. (in that case only the militaries of the world would have access I imagine) I acknowledge that people ARE trying to find newer and better ways to make fuels but they never seem to get very far which is a shame

@TheScientist40 11 лет назад

Actually the atmospheric oxygen comes from water molecules that the plant splits in photolysis, one of the first steps of photosynthesis.

@amacuro 11 лет назад

well you are 90% right. Except that the plant isn't "left with pure Carbon", more like C6H12O6 hehe (since it uses water along with the CO2)

@MrBlackbeltkickboxer 11 лет назад

In secondary school we had crude oil and used a catalyst and burned the crude oil to a certain temputure and the petrol vapour we collected and then the temputure went to high a big cloud and a horrid smell that the while school smelt

@thadude1337 14 лет назад

@TheArmo1 is´nt it demand and need that controls what kind of fuel u use since nobody need hydrogen the demand is practically none?

@OfficeThug 11 лет назад

We use crude oil to get to fuel hydrocarbons because it's practically "free" compared to manufacturing fuel ourselves, especially in terms of how much energy we can gain from the process. It's possible with abundant AND dense sources of energy however, basically striving for sources that are both plentiful and that require little in material/time/energy to utilize. Advanced nuclear reactors, either fission or fusion (preferably both) could definitely pull off CO2-H2O to Fuel production.

@OfficeThug 11 лет назад

Simple hydrocarbons and aliphatic hydrocarbons can be manufactured. Depending on what materials you use, it can be somewhat expensive or downright ridiculous. With CO2 and water, you need to capture/activate the CO2 to form CO (currently being researched), crack water to form hydrogen (800+ C process if using the sulfur-iodine catalytic process), and finally use the Fischer Tropps process. The energy yield from H2O and CO2 to fuel will always be much less than what you get from burning the fuel

@isaacroebuck9514 6 лет назад

First comment in 2 Years. This seems like a really long time ago now.

@Stormrunner0002 14 лет назад

@eyreland This is true but they still must use refined diesel for shut downs as the cooled bunker cloggs all the injecters. I have heard of then running on oil base paint in emergency situations. but you still need the clean fuel for startup and shut down or the engine will be done.

@akkudakkupl 11 лет назад

Coal is known for a nice bit of time. Oil was known in ancient times, but didn't have a lot of uses then.

@inneruniverse17 13 лет назад

The 'Pitch Lake' in La Brea, Trinidad is the largest natural deposit of asphalt in the world.

@FenrirRobu 14 лет назад

@thadude1337 I'd chose water electrolysis or salt water electrolysis (Gives Cl2, O2, NaOH, and some H2 aswell, but it's more complex than just using water), but my main problem is with the wires, so far i have used Al and Cu, but eventually i can see that there is some green CuO and some i guess Cu(OH)2, not even speaking about what happens with aluminium, so if anyone can answer, what should i do, just try to use Cu wires and see if there's a real trouble about my wires or it's just fine as is?

@mrbillybobable 11 лет назад

When I did this last year in school we used actual crude oil

@ElDoctorJanItor 14 лет назад

Does the age of oil affect its viscosity?

@yungo1rst 11 лет назад

there is a carbon aerogel made in association or in full with professor chao gao based in zhejiang university in china that could take in 900 times its own weight in oil for spills if it gets going on production. it is very light and made of carbon nanotubes and graphite.just to let others know.

@naronaroyan323 11 лет назад

Forgot to mention hydrophobic sand I have heard that you can put that on the oil so it sinks the oil down and you can scoop it out of the water.

@98JMA 12 лет назад

I did read the description, but the dictionary is not always correct. For example, I believe the RSC are offering a prize to the first person that can create something tangible that is not made from chemicals. If you turned up with a sample of an element they'd laugh at you.

@kooksies5712 12 лет назад

@stardude69001 no chemical is just a term given to something that is or can be used in a chemical process or reaction. so gold isnt really deemed a chemical unless it is used in a chemical reaction. the word chemical can also be used to describe a chemical agent.. like a reactive compound or substance.

@ya2a16 8 лет назад

Use human hair to clean the surface of ocean ,it works believe me !!

@xDestroyer2x 12 лет назад

That's a another way of saying it I guess, but oil can be easily manufactured. The difference is that it wold cost a little more (thrice as much). So basically oil non-abundance not a problem for chemists

@Arkalius80 14 лет назад

@risbolla The EROEI on oil is much better than other alternatives right now (Energy Returned On Energy Invested). For oil its around 30 I think... (to harvest 30 barrels of oil, 1 barrel is consumed in the effort). So it really comes down to cost efficiency. It's because of the existing infrastructure and investment into fossil fuels that we have, vs alternative methods. They're getting better, but they're not there yet.

@douro20 14 лет назад

Crude oil which is reasonably runny can be burned in diesel engines...they do it in oilfields in Australia.

@HansVanIngelgom 14 лет назад

7:26 the professor is so funny (Sam and Neil probably disagree).

@Roddyoneeye 14 лет назад

You're going to waste CHOCOLATE !?! Are You Barbarians ?!? what angered me about the oil spill in the Gulf of Mexico was learning that so many countries sent to BP their list of assets to help in the clean-up and when BP officials went to the Federal Government with the list, the Feds Refused to allow any help !

@tommos1 12 лет назад

next time theres a spill just call neil.

@agentgates 12 лет назад

I would use a hard but thin welding rod to get rid of most of the stuff as the thin rod can not hold as much of that yuck. After that you can soak them both in a dissolvent.

@Envergure 14 лет назад

@ndyt The batteries are more than good enough for just about everyone. A 200km range is good enough for most North Americans to get to work, the grocery store school, and home. For longer, less-frequent trips you'd have a problem because we have virtually no long-range passenger railway system here. Continental Europe is doing much better in that regard, and I think EVs would be very practical there.

@Sep3lio 14 лет назад

@ElDoctorJanItor Oil is already very very old. As said in the previous crude oil video its created underground from dead animal and plant material. I'm unsure however if the extended heat/pressure under the ground would actually continue modify its chemical composition past a certain point.

@pipsproductions15 14 лет назад

awsome

@llamafruitbat123 11 лет назад

crude oil can't, but different fractions within crude oil can however through a process called 'cracking' where longer hydrocarbon chains are broken down to make shorter ones, making them more useful
