Professor Organic Chemistry Tutor, thank you for an outstanding video/lecture on the Average Kinetic Energy of Gas and Root Mean Square Velocity Problems in AP/General Chemistry. The Temperature of gas particles is important when calculating/analyzing the Average Kinetic Energy of Gas and Root Mean Square Velocity problems in Chemistry. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
I'm in gen chem at college right now and your videos are absolutely saving me, man! Thanks for the taking time to make such high quality and well done videos. Your explanations are so clear and unambiguous, never thought I could learn this shit in 12 minutes!
why is it that you utilize the gas constant for avg KE, but other sources and solutions use boltzmanns constant. How do you know when to use either or?
Thank you so much JG, you really deserve a medal. A stupid question I've got about question 2. I first calculated avg KE, then plugged the value to the physics KE formula (KE = 1/2 m (v.v)), and I got the same result. Just wonder if it's right?
the Boltzmann constant is the universal gas constant (R) divided by Avogrados number (Na). But since he assumes he has one mole of each gas in every equation, Avogrados number cancels out by the number of molecules in one mole. If he was to use Boltzmann constant, he would be finding the average kinetic energy in one particle NOT in one mole.
There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers
This video and this video th-cam.com/video/k3rJs_ioTHc/w-d-xo.html caused a lot of confusion for me, nitrogen is a diatomic gas, it has two atoms, so its formula will not be 3/2RT, it should be 5/2RT and have a different internal energy. at least according to your other video, so which one is right?

Thank u bro i have my final today
Brilliantly done!
First time saw your video...how beautifully explained😍...helped me a lot...thanks😄

holy shit. 2 hours of lecture become 12 minutes . ty man
Shouldn't it be the boltzman constant?

Sir please ,make a short video on the derivation of average k.e per molecule.
Thank you for this Video.... Thumbs Up
The videos are such a great help. Thank you.
God bless you sir 🎉❤
Anyone know why some use R= 8.314 and some use boltzman constant. I'm not sure which one to use.
If you know the number of molecules of a gas(like 200) then use the Boltzman constant.
If you know number of moles of a gas, then use R
@@autumn_auburn Thanks for the late reply, but fortunately I figured it out in time! :3
im so glad you asked this question
@@jonathansmith5534 good luck man!
Thank you so much, you explained it so perfectly. Gonna subscribe
i am very confused in average kinetic energy and total kinetic energy some use degree of freedom in avg while some say its in total
Wow man ur voice is handsome and keep uploading such videos i have subscribed your channel
wtf
This is great sir
thank you, I am passing chemistry because of you.
pro trick : you can watch series at KaldroStream. Me and my gf have been using them for watching lots of of movies during the lockdown.
@Zain Nicholas Yea, been using kaldrostream for months myself :)

i wish i could be a member for the longer vids but i brok
Brilliant 💕
Damn good explanation and nice flow with the explanation. Thanks for the help!
Nice and easy way.
5:25 yes, work makes me mad too
This is soooo helpful.. Thanks
is root mean square velocity the same thing as average molecular speed?
thanks

It's for n=1
Hi when do younuse the boltzmann thing kb
Isn't helium a diatomic gas? Shouldn't the mass be 0.008kg/mol instead???
Better use R =1/12.
more easy more exact
you mean 25/3
Than isn't exact.
@@subasan4798 this is right
KE of gas =3\2kBTor 3/2RT
Just a question
10:19
"Tenmature"
Why we didn’t use the equation with n?
sarah Alabdulla i think he did a mistake
Thaaaaankuuuuuu veeeeery muuuuuuch
I'm a big fan.
gas constant is already 8.314
