Mr. Anderson, first off I would really like to thank you for making these videos. They were my life-saver last year for AP biology, and are helping this year in AP Chem. Many times after watching your recent videos, I feel you are talking too fast, especially when explaining difficult/new topics. If you could slow down and pause every few seconds, it will be much easier to understand your videos. Also, many times after watching your videos I still don't understand the concept. If you could break down the concept even more and walk us through the whole thing, instead of trying to cover both the concept and the equation in ten minutes, it would be very helpful. I hope you will view my comments as constructive and will incorporate them into your future videos. Thank you!

The perfect man. The man that knows everything.

holy mother of God this was so useful and well done i was able to derive the V_rms before you showed us at the end. and all i needed was for You to show me what Temp equaled! thank You so much!

Thank you for making this videos, you realy give people something keep up your good work.

This is some amazing content, thank you!

u've been my pop-sci go-to for physics and chemistry akin to wiki articles when i'm too lazy to research. ty for not bastardizing well documented high school level stuff (some lectures are indeed borderline graduate level but idk)

I love your videos! Thank you!

I don't understand why this doesn't get more views...

That is our world where we live !

Thank you! Very helpful.

Imformative and interesting.

a very clear understanding of temperature!

Nice one.. 👌

Unrelated but can you cover Quantum Mechanics like discrete energy levels of atom, photoelectric effect, emission and absorption spectra? Thanks very much :)

Can you explain about kinetic theory of gases which is formula like p=1/3p(c^2)

AMAZING

God bless you

If we're talking heatconducting molecules, shouldn't it rather be called nanoscopic instead of microscopic?

Thank Youu

Sir, please make videos on surface tension and *elasticity(=stress/strain)

Saving me 🙏

I'm happy that the gas molecules travel randomly, otherwise those with a speed above 343 m/s would make an awful noice.

Nicely done, but remember, chemistry is your friend!

Now explain how molecules lose kinetic energy if it is constant when transfered

Love from Bangladesh

if two bodies have same temperature then will they have same average k.e??

Not necessarily. It is only strictly true for gasses, that temperature is directly determined by the average KE per molecule. It also is only the translational KE that contributes. Rotational and vibrational modes will also store kinetic energy, which is how different flavors of gas can have different molar heat capacities. In general, two gas types with the same molecular shape, should have nearly equal molar heat capacities, e.g. Oxygen and Nitrogen. If the total KE mattered, then all gasses would have to have identical molar heat capacities. All noble gasses do have identical molar heat capacities, since they only have translation as a mode to store KE. It is only the translational KE that governs the proportionality to temperature, because only the translational KE determines whether two flavors of gas in thermal contact would be at thermal equilibrium. Put Oxygen in Tank 1, and Argon in Tank 2, and put a copper wall between them so they can exchange heat. The O2 has more internal KE per molecule at the same temperature, because rotational modes of KE storage also play a role. The temperature of a solid or liquid is determined by what average internal KE per molecule you would get, for a gas that is in thermal equilibrium with it.

can we just say that its the total average sums of all the molecules

Dude im in 7th grade and my teacher assigned us this vid... Let's just say she's crazy.

:) I understood.
