I liked how you gave all your references but mostly the salt concentration affecting dissolved oxygen was interesting. Though i still don't fully understand Eutrophication.
There are certain elements that serve as food for living things such as trees and underwater plants. These are nutrients that help them grow, such as... phosphorous, nitrogen, etc. Just like humans can get sick from consuming too much, so can plants. This makes them grow at a rate higher than normal, not allowing the ecosystem in the water to work the same. Fish may not be able to swim in open water because the plants in the water are so overgrown. These excess elements in the form of food for the plants, usually come from waste from factories and stuff like that. So that is why the speaker talked about trash. Eutrophication is when a body of water becomes extremely filled with those plants, phytoplankton, etc. and there is not enough space for "normal conditions" for fish, humans, and other living organisms! I Hope this helped :)
Great info. The o2 air saturation was not something I'd considered regarding liberating oxygen from water, and didn't know if water could hold addition Oxygen
I thought animals "breathe" in the oxygen from the water molecule, itself. Water is H2O. I thought they just took the O, and the hydrogen would evaporate until it joined with more oxygen to become water again. I don't have a clear understanding of how dissolved oxygen doesn't connect to the H2O molecules and become h2o2. Or, for that matter, why other molecules (like nitrogen) don't connect with the H2O molecules when they enter and dissolve in water.
Not quite. The biggest misunderstanding is the strength of the forces that hold the chemical bonds together. Thereby resulting in a stable molecule like water. H20 is a molecule held together by covalent bonds and the way Oxygen and Hydrogen are bonded together isn't a casual bond . It's incredibly strong. There is a strong pull of those 2 to each other that's why they are a bond. You can't just pick molecules apart casually without applying force that is stronger than what brought them together in the first place. For example if you have NaCl ( Table salt) You cant just get the Chlorine or Sodium from there casually. If that was the case our universe wouldn't really have molecules. I'll give some numbers: bond dissociation energy of water is about 463 kJ/mol. which means you need that much energy in KILOJOULES!!! to break apart just 18g of water. :(. Imagine a bond of water :( That's why to decompose Water into Hydrogen (H2) and Oxygen (O2) for example , it takes a process called Electrolysis ( Which means applying electrical current to the water solutions with an electrolyte and electrodes to break it apart) . This same process is what you would use to to decompose NaCl and other molecules . Note that electricity is used. Which is something that uses a lot of energy. Not boiling or melting. If you boil water, The water vapour is still H2O steam, the chemical composition doesn't change one bit. Only the state : i.e. It's no longer liquid water but gaseous water. PS. Nitrogen molecule is not very reactive... It occurs as N2. And appears satisfied..
water = Hydrogen+Oxygen so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)
Fantastic question. You are eluding to hydrogen bonding . And it is exactly how it sounds, which is a Hydrogen atom from one molecule forming a weak but significant bond to another Electronegative atom( Nitrogen /Fluorine/Oxygen) . Often times, the molecules can then arrange themselves into web-like structures. A picture will this explain clearer. Any person interested in water of Fluids or any material science at all should definitely read and understand INTERMOLECULAR FORCES as they explain so much . Things like surface tension, solubility , density(especially that of water ) , viscosity and many others are explained by hydrogen bonds
Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.
If the oxygen the plants produce is consumed when the plan dies, the fact that the plants are many or few doesn't change the oxygen content of the water and it is incorrect to say that plants are one of the ways in which oxygen is introduced into the water, because those plants will die in the water in any case.
Communication with student : 1. by visual 2. by talking 3. by listening 4. by feeling 5. by action unfortunately, all University only have talking and listening. 😔. thats why many are C students. or even fail.
Wanna care for the fish and the ocean ? Stop overfishing to fulfill your eating habits. No matter how much you recycle, the only way to truly minimize your impact on the enviroment is to move to a fully Plant Based Diet. Good luck. Other then that great video. Thanks !
3 things: Amazing graphics, simple and to the point info. best wishes for future videos.
WHOOOOO
NICE GREEEMPHICSS
That is a lovely video with a lot of information in it .... Thanks for uploading that
Thanks allot! Was searching for the awnser why warm water holds less oxygen but found allot more! Thank!!
This 5 minute video explained my 4 weeks worth of classes for my environmental engineering class.
The graphics are satisfying af huge props to the editor. I also appreciate the informative video. Thanks

Very lucid and informative.Great Work. Eutrophication description could not have been better. Hats Off!

What a nice and simple illustration... It helps me much in understanding how those oxygen come in and come out of water... :)
This is very well done! a lot of well explained content.
The best video EVER! thanks a lot for this chrystal clear explanation
This video will be considered a land mark for our time, in time I promise you, very well done.
Concise and brilliantly explained.
Very informative! I needed this most!
Awesome. It is simply awesome. I learnt lots of things from here. Absolutely amazing.
Thank you very much. I really struggled for this . Wow ! What an amazing video. Concepts got cleared 😊
Great job! Really nice quality video and super clear.
this explains it so simply and so well wow thanks
This is indeed a very informative video, with a great message! Thanks!

Good job for basics of DO
Thank you so much!! this video was really helpful, straight to the point and well explained!❤
I love the animation of your video ... 😆
That was really well done! Informative little video.
Great job💯👍👍
Wow such a nice explanation
Good to understand,easy to explain
Love it! Great video, really helpful, informative, and inspirational. Thank you so much!
Love this video explanation! Very clear! Thank you!
Great video. Thank you so much for taking the time to make this.
Very well explained
Brilliant, along with a lovely commentary :D
Thank you.... It is easy to understand and funny also...
Great video!
Thank you, it is a easy to understand and fun video to learn science topic from.
Nice video to watch, it helped me a lot to know the concepts,
Excellent video!
water = Hydrogen+Oxygen
so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)
only dissolved!
Beautiful work :)
Thanks . love from Afghanistan
Thank you. the video was very well done
excellently explained
Very helpful 👍
This video is great! Keep up the good work lavyu
Amazing video, thank you.
Thank youuuu, this helped tons
Thanks this video was great! Very helpful! Keep up the good work!
How does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?
Fantastic question. You are eluding to hydrogen bonding . And it is exactly how it sounds, which is a Hydrogen atom from one molecule forming a weak but significant bond to another Electronegative atom( Nitrogen /Fluorine/Oxygen) .

@herminenamakalu4171 nice. We call them bridges in Spanish but it's the same thing
awesome video! very informative :D
which program/app did you use to make this?
Thanks for this video
Beautiful video, well done:)
It's possible to remove the Dissolved oxygen?
Boil the water
Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.
Very informative video!
good job!
which is higher oxygen... hot water or cold water?
very nice video, Thanks!! 😁
This was very helpfull
Oh good I have a test tomorrow thanks!
Good video
Thanks for the information :)
Cyanobacteria do not undergo photosynthesis. They make their food chemically (chemosynthesis)
Thanks dear🤗
That was remarkable.
Thanks so much !!
how cool is that intro
my father's farts are dinoflagullates also...apparently a dinosaur crawled up into my father's ass and then died when he was young
Could you please let me know why boiled water doesn't contain dissolved oxygen in it?
Because it's too hot.
The hotter a liquid is, the less dense it is, therefore the less oxygen it holds.
Well nice voice
awesome video
If the oxygen the plants produce is consumed when the plan dies, the fact that the plants are many or few doesn't change the oxygen content of the water and it is incorrect to say that plants are one of the ways in which oxygen is introduced into the water, because those plants will die in the water in any case.
Wow. Again youtube surprised me. Thanks
Thank You!
For a moment there I thought she said dino flatulate. lol a.k.a. dinosaur farts
very helpful
wow cool

unfortunately, all University only have talking and listening. 😔. thats why many are C students. or even fail.
Plz tell me the procedure of "determination of dissolved oxygen in drinking water By Do METER "??????
I hope in recent years you've changed the voice over people. She sounds so scary.
so at 2m in you state that plants / alge suply o2 ... then 10 seconds later you claim the opposite by saying plants use o2 to live.
H.P.C.M.S was here!
Perfect
Ah that is the dissolved
yes that is the dissolved
when you make something to be understood
Hats off
Awsome
imagine a world where we weren't surrounded by air YOU WILL BE ....... DEAD
Had to watch this 4 school stfu and lma
