THANK YOU!! so helpful!!

Teacher, just kick the global-warming nonsense and focus on the empirical evidence.

You say that life was not possible when there was no oxygen in the atmosphere hence no ozone layer to protect life on EARTH. However, there was life in the absence of ozone layer since 10 m of water suffice to filter UV light from the sun. A few milimeters on a damp soil does the same to protect against UV.

Great demonstration!! Thank you

Isn't that interesting ? Thank you for the lecture.

I don't think I've ever comprehended a lesson so well. Thank you so much! There was so much detail, yet the explanations were concise and clear!!

Thank you so much ❤ it really helps me as a student who struggle with this long, thick book.

Consider correcting the errors in the slides. Very good otherwise!

So the warming oceans produce co2. Has anybodies measured or calculated this quantity? What was the temperature differential in your experiment

Wow. Do you realize that this experiment just disproved CO2's effect on global warming? It's clearly the other way around. It's the global warming that's causing more CO2 in the air. Why? Cold water holds more CO2; warm water holds less CO2. It means when the Ocean is warm, it won't hold as much CO2, so there is more CO2 in the atmosphere. It's not that it's CO2 that's causing the rise of temperature but that the rise of temperature is causing the Ocean to let go of more CO2 into the atmosphere. And what's causing the Ocean to get warm? The sun. The rise of solar activities causes the Ocean to become warm, and when the ocean becomes warm, it lets go of more CO2 into the air. So any claim that human CO2 is responsible for global warming is dubious.

So is this why cold sodas feel more carbonated and fizz a lot less when you open them than a warm soda???

It's understood that CO2 is absorbed better by cold water. The question is, with the atmosphere being comprised of only 0.04% CO2 and the oceans being as immense as they are, how much can this trace amount of CO2 affect ocean acidity? Not a significant amount. I'd venture. It's the same for the idea that a trace gas can warm the atmosphere. The Ideal Gas Law makes it clear that CO2 can warm the atmosphere no more than it's mass percent, about 0.04C per 1C warming of the atmosphere.

Thank you very much for the detailed explanation!!

very nice demonstration 🤓👍

This is the clearest I've seen this explained, thank you. You are clearly passionate about this field- it shows, made this a joy to learn from.

I don’t know why, but you look like XQC’s mom.

not helpful

Greetings from Turkey IZTECH teacher you are the best!!!

لحمدالله ما فهمت شي

I have my gen bio college exam tomorrow and this video helped me SO MUCH! Thank you for posting this!

Great video and great info. 👍🏻

great presentation, thank you!

River and crick water

thnk u Miss!

What an amazing experiment! Exactly what is going on and absolutely relavent to world events of today! I wish everyone could see and understand this. Hopefully one of these students today has ran with this understanding and knowledge.

Stay with nom-difficult job Jake

We should store carbon dioxide in ice in the artic.

how many times she said Oh, i'm sorry?

What a way to explain in evidence Just WOOOOOOW

Hello! There is a problem regarding my microscope... Basically earlier the coarse adjustment was working, and the microscope was going up and down accordingly... But now it's not working ( I think after I took the objective lens away from the slide by using the coarse adjustment, after sometime it got out of control) plz help in resolving the issue, it's a sincere request 🙏🙏🙏

Excellent

Oh goody! It's fairy fable time! NOT! Ignorant evotards!

Very good professor, continue always !

very good

I finally get it! Thank you for your help 🫂

Loved the video and explanations! Thank you!

This experiment proves that CO2 in the atmosphere is increased by the sun. The oceans hold nearly 96% of the earth's CO2. When the sun warms the ocean, more CO2 is released into the atmosphere. Validation to the scienctists who use earth core samples and the real Data Al Gore shifted to tell his lie. They know CO2 increase in our atmosphere FOLLOWS global warming from the sun. Co2 does not precede nor cause global warming, it FOLLOWs it. Just in time for the spring flowers and green plants who NEED CO2 to grow and make our food! Sun helps them get their needed CO2 on time! God knew what he was doing. We know what you are doing lady, not asking kids to think, just giving them the narrative which is leftist propaganda. Stop lying please!

Great demonstration Mrs. Foy!! Thank you very much.

wow, this is a great demo and it explains clearly thank you very much.

Switches that guy to the 'non-difficult job' straight away...

Hi! Great experiment and very well explained. I just wish that the results had been shown after the tablets had time to dissolve completely. Reactions normally happen faster at higher temperatures, so it would make sense for the hot water to dissolve the alkaseltser much faster than the cold, which could have created a much larger difference in the volume of gas at the start. Another possible issue is that because the tablet in the hot water dissolved so much faster than in the cold water, it might have less time to dissolve the co2.

Is there any acid added to the water:))

Thank You. I can use this knowledge in my fishtanks.

Nicely explained thank you.

Thank you so much 📌❤️

wonderful video

You're an amazing teacher😌🔥

Thank you. You explained it so well. I have such a clear understanding of the process now.

What was left out, Chromium Picolinate, and Selenium are helpful supplements.

this was so helpful!! loved the cake analogy :)
