In a gas, molecules undergo collisions with one another. How far do they travel, on average, between collisions?

in my book the small part about relation between Vrms and Vrms relative wasn't mentioned and left me unsatisfied. thanks for the video.

Thanks for the lecture really helped a lot 😊

Excellent explanation Sir!!

12:26 Dear Professor, how rms velocity can be replaced by average velocity with square root 2 intact?

[medardjosephat]

thank you sir for your work kindly I would like to ask on the relationship above what does letter K implies an what is its value

Dear professor, Nobody explained me why we should take <2(vA.vB)> = 0 till you. You said why average of all dot products cancel out. By Allah, I loved it. But, Most of others say, "they aren't correlative, so zero" It seems so confusing. Are they explaining it correctly?

may l ask if wads the difference between the formula for mean free path taught in this video and the formula 1/square root 2ppid^2
and RT/square root 2pi d^2NaP note that Na is avagado's number

the pressure unit is"pa"?
why isn't it atm?
