Dissolved Oxygen

That's a cute little video bur with very much impact

your voice is so cute and charming !!

Thanks so much !!

How does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?

This 5 minute video explained my 4 weeks worth of classes for my environmental engineering class.

imagine a world where we weren't surrounded by air YOU WILL BE ....... DEAD

good job!

The best video EVER! thanks a lot for this chrystal clear explanation

Good video

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

Thanks for this video

Evolutionist don’t care. They only think about the development of life. And forget about the many ecosystem’s that are vital for life. How did Darwinian evolution develop and sustain these. Think!!!!

Thank you so much!! this video was really helpful, straight to the point and well explained!❤

Well nice voice

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.

This is very well done! a lot of well explained content.

Very helpful 👍

Very informative! I needed this most!

Very well explained

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.

Love this video explanation! Very clear! Thank you!

wow cool

Awesome. It is simply awesome. I learnt lots of things from here. Absolutely amazing.

Thank youuuu, this helped tons

when you make something to be understood

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)

how cool is that intro

That was remarkable.

this explains it so simply and so well wow thanks <3

which is higher oxygen... hot water or cold water?

Nice video to watch, it helped me a lot to know the concepts,

Thanks allot! Was searching for the awnser why warm water holds less oxygen but found allot more! Thank!!

cherrs cherrs

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.

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.

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.

Great job💯👍👍

Great video!

I love the animation of your video ... 😆

Thanks . love from Afghanistan

Had to watch this 4 school stfu and lma

I hope in recent years you've changed the voice over people. She sounds so scary.

Amazing video, thank you.

Ah that is the dissolved

Cyanobacteria do not undergo photosynthesis. They make their food chemically (chemosynthesis)

very swag
