Molecular Kinetic Theory (simple derivation) - Kinetic Theory (Lesson 4)

Lesson 4
The kinetic theory of gas allows us to derive the equation of gas pressure pV=1/3 Nmu^2.

In this video, we look at what the root mean square speed is and how that is used in the gas pressure equation.

Lesson 3
Two versions of the empirical ideal gas equation:
pV = nRT
pV = NkT

Lesson 2
Boyle's law, Charles' law, and Gay-Lussac's law, and the combined gas law

Lesson 1
Describing an Ideal Gas - Moles, Molar Mass, Relative Molar Mass, Avogadro Constant

I am a fellow Physics teacher and now a huge fan of you and your channel! Beautifully pitched at GCSE and A level students - succinct and lucid. Thank you so much for all of your efforts and generosity. I am in awe.

[MidnightStorm]

Thank you so much! This was very clear and simple to follow so keep posting more!

[sanketpathak]

Explained in a very simple way, thanks!

[jizzyjjarold]

Hold on. But isn't delta t the duration when the particle is colliding with the wall and experiencing the net force? After all, force = the change in momentum over the change in time. And the change of momentum happened only when the particle collides against the wall to experience a net force in the opposite direction of its motion. The delta t you use is for the particle to come back to its initial position (distance over velocity) and not the duration in which the particle experiences the net force by the container walls.

Woh.. What an explanation, simple &understanding ❤

[starman]

thanks a bunch, clear and precise explanation

[NoMatterWhat]

But how can time of impact equal total Distance 2x/speed as It is the time for which collision happened, so distance travelled is negligibly small during collision, why did you consider time of impact as the total time taken for The particle to come back again?

[harrambaloch]

It solves my big problem thank you so much stay blessed and keep it up 😘

[adarbarandalgic]

How can we substitute the value of the time between collisions as a contact time for the impulse equation?

[KrishnFolk-pirv]

Perfect video for students thanx a lot teacher 🙏🙏💐💐💐

[GL-Broz]

In india this is 11th standard physics 😣

[raka]

woah that's fantastic. now i'll be able to remember it.

[jonahmedics]

Thank you very much am wordless it helps a lot thanks fr

[copiryte]

Can you go through the more complicated derivation where the time between collisions isn't used in the rate of change of momentum I can't find any videos on youtube explaining it.

[Tabbyisfriendly]

yo it was really a good explanation
but can you explain the last rms part

[wayoflife]

I have a doubt
In here do we assume that acceleration =0
Since you consider delta t=2x/u
In the video 2:06 part

[Dark-tkxu]

Since when speed (which in this case is 'u') is a vector? Why do you have -mu? Is u speed or velocity?

[wuttinanthailand]

The only problem here is how do we know that divide by 3 is correct?

[maltzXD]

Why can we use t in distance / time? The t in impusle is the contact time with the surface. The travel time t in other parts of the box has nothing to do with the contact time.

[amirhamza]

Why the time of impact is time taken to reach where it started
