Best online teacher!

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.

My left ear is smarter now. Thanks!

Really appreciate these fantastic lectures. Thank you!

This video definitely helped a lot. Thank you!

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

great demonstrations!

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

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. :)

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

Explained it vary well thank u!!

Thanks for the help

It was really helpful I completely understood...

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

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

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.

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.

Mass is cool

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).
