Thank you so much. This makes so much sense, I love how you went through the examples. It really helped

[@imbisatfajjar]

Better teaching then my teacher ❤❤ love from Pakistan

[@Demi305]

once again, thank you so much for this video Cognito!!! it really helped me to understand the whole concept !!!! you are just a brilliant teacher and you deserve to get at least a million subscribers

[@hannahfishx9306]

thank you so much for this, i've use your videos for my physics, biology and chemistry tests. I could finally understand the topics and gain interest in the subject of science!

[@sammyflipaclip]

as a student who's suffering to understand these, thank you Sir. This greatly helped me and saved me life

[@faqruddinaadil]

this man is just amazing i am trying to solve these kind of problems from yesterday night after seeing his video my all doubts are clear... thanks bro

[@mikemyers38]

Your videos are superb! You have no idea how much we Physics teachers appreciate you! Keep up the good work. :) S2 S2

[@harrietkayereyes9832]

This is so good. I literally understand the adiabatic process because of this video ❤

Greatest teacher on planet earth 👌

I am

[@solarpunch333]

Could you also use the equation: pressure=k/volume ?

[@babybunny4994]

Thank you so much ☺️ it is really useful for when I need extra help during online class 💞

[@universeusa]

Awesome, thanks! 👍🙏

[@Cognitoedu]

Thanks Jake! Hope the revision’s going well mate 🙌

[@cornflakey-n7k]

Thanks so much this saved me hours!

[@Whynot-my5fx]

I was absent the day this was explained in class but now I understand it thank you so much💗

[@MidnightStorm4990]

Doing A level chemistry and I realized that the PV = constant is similar to the PV = nRT

[@heroldmuashekele9024]

So useful for physics exam revision keep it up big ups🙏👍👍👌

[@SP-sq6rr]

If you left is as kPa, would that lose marks? Does it have to be converted into Pa because that's the unit for pressure?

[@khaif.3376]

the k just represents 1 thousand

How to calculate pressure using oil fluid in a vertical cylinder if it is pressed 10 mm while the rod length is 200 mm, the diameter is 1.8 mm and the rod is 1 mm. Please advise and provide a solution with the formula.

[@channelakhaura3260]

Thank you sir,😊 from Bangladesh

[@tmlyrics2145]

Can you use the equation of saying the volume has decreased by x5 for example ,meaning to multiple or divide when the pressure increases by that x5

[@icarus1378]

How did you explain this better than my professor even though English is not my first language? Anyways thank you, sir!

My friend recommended me about your channel.

can you please tell me what software are you using to show these things?

[@abdulqaderomeed999]

There is something that confuses me, I think this only works when the variable we change is volume. If we are changing the pressure, as in a ballon, then the volume would increase instead of decreasing

[@amanysultan7455]

Can someone help me with this question A gas with volume 100cm3 at pressure 300kpa is decompressed to 100kpa what is its new volume?

[@bigboi8879]

it's 300 cm3 Because pressure and volume are inversely proportional, when one decreases, the other increases. So, as the 300 kpa is decompressed to 100 kpa and 300/100=3, you will have to *multiply* 100cm3 by 3 which is 300 cm3. Hope this helps and correct me if im wrong.

How abt constant pressure???

[@joannadaniel9396]

thanks

[@emz.chaotic.reading]

are we supposed to know the constant for specific gases? bc if we do i’m completed screwed

[@YashB_.06]

no u don't

[@YashB_.06]

if you're doing aqa the spec says: Students should be able to calculate the change in the pressure of a gas or the volume of a gas (a fixed mass held at constant temperature) when either the pressure or volume is increased or decreased.

[@frankjames1955]

SOmeone told me the formula for finding the volume of compressed gas in a cylinder .. P1 V1 =P2 V2 ... i have no idea what this is but i think there is a much simpler formula.. either P x V / atm.. or (P+atm) x V / atm .. as i contunue for days to find the answer i get alot of conflicting information .. as if its a matter few understand properly

[@icyyyy3734]

It’s just this pv constant equation basically if they give you two volumes and maybe one pressure or vise versa you can use p1v1 = p2 v2 just inserting the values and solving
