What is density?

[@aliahsan6604]

Richard Louie, you are the best man alive. Thank you so much for helping me understand the topic of chemistry. I hope that in the recent years, you become a world class teacher.

[@daniyalkhawaja4604]

Best online teacher!

[@53bload53]

My left ear is smarter now. Thanks!

[@ShukokaiStu]

Really appreciate these fantastic lectures. Thank you!

[@charbarr_22]

did your teacher send this to you?

[@mikecameraaction.]

Sir i appreciate a lot for your work

[@drumtwo4seven]

Awesome. The best of the world wide web 👍

[@xOxAdnanxOx]

great demonstrating the concept

[@victoriadickson5991]

Great one

[@greatsaiyagirl]

Very helpful video! Helped illustrate the relationship between mass, volume, and density perfectly. I was a bit confused before, but now it makes perfect sense. :)

[@mantoshsahumks9970]

Great effort...but why did you stop uploading video...you should continue for the students....

[@VirenderKumar-bp1hm]

Very good sir

[@Gabriel-ut1qz]

I came here for learning physics and ended up learning both Chemistry and physics.😂

[@urfavlolobaji]

Gabriel I want to learn chemistry ⚛️

[@ManzilSafarAurBaateinOfficial]

Great lecture

[@nduluechristabel2951]

Thanks a lot sir u really really helped me

[@fatimashah9644]

Thank you! I am a counselor at community college and will be recommending my students to your website!

[@richardlouiechemistrylectures]

Thanks for the feedback. I hope that your students are doing well.

[@btterbetraya505]

Thank goodness for this! I have a density quiz and a layers of the earth quiz and I was so confused! Thank you so much!!

[@Flo_Doh]

Natalie Cray _190 I hav a quiz tomorrow on density volume and mass

[@jenngzz11]

Thank you! That was great :)

[@krichudayy61]

thank you this video was very helpful :) easy to understand, very interesting to learn about 😁

[@sanakatiry253]

It was really helpful I completely understood...

[@dhavalpandya978]

rubbing alcohol density is 0.78 not 0.87...

[@richardlouiechemistrylectures]

Thanks for the correction!

[@dhavalpandya978]

@@richardlouiechemistrylectures Sir, I am very inspire of your knowledge that try to simplify chemistry more than our college profesor.

[@rachelmarvin2781]

Awesome and thank u so much for giving more info about density.

[@hannahash5854]

Thanks 🙏 Great video!!! Helped me a lot.😁😁😄

[@CrotchetRocket]

you just made me the smartest dude at the bar

[@josephz8]

I love this video so much I have a summative tomorrow and this helps so much thank you

[@alvelymondragon33]

great demonstrations!

[@etchpak]

thanks for usable information.

[@merrickq9993]

Explained it vary well thank u!!

[@themothahustlasons4017]

thank you my son needed help thank you so much

[@richardlouiechemistrylectures]

Glad it helped!

[@deliboibruh5374]

Thanks for the help

[@OMGdeals10]

super sir ......keep it up

[@taladiab3502]

Thx

[@josejasso3298]

Your explanation of why the aluminon foil box does not sink is wrong. 1. the box is filled with air, 2. If you have the same temperature and pressure density does not change. 3. the aluminum box flotes for the Archimedes principle, that is why boots float.

[@richardlouiechemistrylectures]

You might have a point. At about 6:13 I point out that the box is filled with air. Since air is less dense than water, it floats in the water. I probably should have emphasized that the box is mostly air, and that the reason the box floats is because air is less dense than water.

[@Naveennci]

great sir

[@LandonOhanian]

Thanks alot

[@AsadKhan-bi5jg]

Hats off from pakistan :) thanks for information.

[@karinav736]

Thank u!! It is helpful

[@yorifuteki50]

Thanks a lot. It is very helpful for me as student. (I am not good at chemistry :p )

[@hugoboss1061]

it was a really good video

[@shadowbloop]

you cant hear this guy

[@richardlouiechemistrylectures]

I used a wireless microphone that unfortunately recorded the sound in mono, so the sound only goes to one speaker. If one of your speakers doesn't work, you may not hear the sound. Sorry about that. Try listening with ear phones (you'll only hear sound in one ear phone).
