Temperature and Gas Solubility
Вставка

- We know about solutions and solubility, but we have typically examined solid or liquid solutes dissolved in a liquid solvent. Did you know that gases can also be dissolved in liquids? Their solubilities depend heavily on temperature, so let's take a closer look at this relationship!

*"He knows alot about the science stuff, Proffesor Dave teaches me more than my actual chemistry teacher" * :)
I love this style of making videos... No spoonfeeding, no beating about the bush just straight to the point explanations
Seems like just yesterday you were helping me with my organic chemistry, now I need your videos for anesthesia school... Thanks Professor Dave!
he is a real scholar, a real scholar who knows his subject real deep and can explain stuff
Awesome professor 🤓
You have explained the topic very well
hello sir im kishore from india im a big fan of ur lecturess
just Too good... Crystal clear 🔮
Professor Dave you da shit. thanx for helping me learn and pass my chemistry course
why does the solubility of CaSO4 decrease as temperature increases?? please help!
you aint recieve your help he eh e eh ehe h
Loved it😘❤️
very well explained. but where is comprehension?
I think he got rid of it... He has it in his earlier videos but not in his newer ones.
Me acabas de salvar la vida!!!!
Thank you very much for your videos Prof. Dave. However I have a comment: I like your videos more when you talk more naturally (like your old Orgo videos). While still very informative, videos like this one end up sounding a bit monotonous.
Greetings from Brazil!
he sounds really upset, i hope he's okay :(
Awesome...👍🏻👍🏻👍🏻🙏🏻🙏🏻🙏🏻
1:36 why oxygen dissolve in water ? Bcs oxygen is non polar and it can make dipole-induced dipole interaction with water.
4: 35 solubitlity oxygen in trmperature normal (27⁰)
Very helpful sir
From india :)
Hello, thank you for your vedio, is there any book that describe gas solubility mechanism?
i love u it helped me so much 😍
I think u would look adorable when you cut your hair and shave your beard..just wondering though... But this is the identity of Professor Dave soo... Cool
2:39 approximate these type of interactions. *what does that even mean??*
IM DYING HERE PLEASE HELP
other molecules that make H-bonds, or at least have strong dipoles
I learn all sience here by your videos..then Books🙏🏻💜
And now you need to learn english.😂😂😂
@@xiibsahildongre5070 its ok bro he must have wrote the comment very fast😂
science* than* koi ni bro hota hai
So this means when we provide pressure to any system including lets say CO2 and water so more of CO2 molecules interacts with water hence saturating it right ?

nice knowledgeable video
Chemistry test on Tuesday
Same here I have a test tomorrow
My test is dueeee in a little bittttt
resembling jon snow
Hii sir u lectures r really very useful for me ...... I have a doubt.. u r saying soulbility depends on dipole dipole interactions .....dipole moment is a property of a molecule then howcome pressure can increase the soulbility means how can it exactly effect the dipole nature of gas??????
oh it doesn't change anything about an individual molecule, it's just in a closed system greater pressure just means more vapor, or more molecules in general, so more of them colliding with the surface of the liquid and more end up getting in there and dissolving.
@@ProfessorDaveExplains ohhh yes ..thanku sir...
5:11 - 6:01 - Prof. Dave keeping it real! #climatechangeisreal
Why is methane more soluble than oxygen as the gas solubility graph shows? That doesn’t make sense to me. Sure, methane is more polar than oxygen in isolation. But in water, the oxygen gets polarized via the dipoles of the water molecules. Hydrocarbons tend to not get polarized in this manner as the carbon is not all that electronegative, leading to decreased solubility with more carbons. In fact, I’ve only seen hydrocarbons get polarized in 2 ways, those being:
1) Addition of halogens, halogen replaces hydrogen and the molecules become polar and unreacted molecules still get polarized by the presence of halogen, small amount of acid forms in the process
2) Double bond reaction with water, oxygen bonds to the carbon in the double bond and forms an alcohol, which is polar, a hydrogen gets kicked off the water molecule
So why would methane be more soluble than oxygen in water?
Thank you jesus 🙌🏽
Hey its proffesor jesus
help me on a testttt pleasee
Pls tell about yourself in a video
check out my "ask professor dave" series i talk a bit about myself!
@@ProfessorDaveExplains thanks sirs..your big fan
Helpooo meeee
