Dunno why you are so underrated. You’re like one of the best educational youtube channels out there IMO.

[@ScienceShorts]

Aw, thanks!

[@rafathchowdury1968]

Have to agree here

[@hannkwak8992]

Charles Boyle, also known as Jake Peralta's best friend (thank you for the video btw)

[@colarey]

2:22- Boyle's law whole notes

[@adsverse7526]

Day before my paper 3 exam and you are honestly my saviour! I love the detail you go into, considering every aspect from uncertainty to clear diagrams and of course the written method. The list of carried out practicals to accompany on Malmesbury Education is the icing on the cake!

[@joevenables3393]

Thank god for advanced information

[@colarey]

Charles law whole notes- 5:56

[@ascend9545]

I have watched so many of your videos to help my revision for a level physics, this is the last one i am watching before i go into my final exam! thanks so much for all the help! you`re doing a great thing here!

[@coolman113a9]

Did you pass?

[@umangakithmini5009]

Wow great explanation....thanks for explaining the analysis part as well because most of the people out there just state how we should do the experiment without any analysis whatsoever👌🙂

[@LeCocoRain]

Mr Rees would you mind adding this back into the required practical playlist just for ease of viewing?

[@joshvir262]

Great video!

[@schmuckthenonce8816]

To everyone here sitting the exam, you can use PV/T=constant quite often to work out the new temperature or whatever. Try it out if you haven’t :))) Good luck

[@AbdullahiIdri2001]

very insightful
thanks, shmuckthenonce lmao

[@Josh-qg8jv]

Yes lad well in, great video

[@PreetKaur-sf5vq]

Is this for every specification of A Level Physics or just AQA?

[@David-fc3mg]

thanks this is great recap for my exam tomorrow

[@rafathchowdury1968]

Can you do exam question tutorials please

[@parallel4]

Hi sir, I have a question about some things in this video.
For the 1/V against p graph, wouldn't the gradient be 1/(pV), because the vertical axis is 1/V and the horizontal is p, so (1/V) * (1/p) = 1/(pV)?
Also, why would we expect that graph to go through the origin? Surely 1/V can never = 0 because then you would get 1 = 0?
Thanks so much for the videos you make, they are a great resource :)

[@joshhampton7235]

Oh it’s because as you see disclaimed they’re in the wrong axis, P is Y and 1/V is x. Therefore change in P / Change in 1/V is just PV/1

[@thomas4073]

I think you're right that 1/V can never truly = 0, since when that is the case V will also be 0 (since the gas' temperature will be at absolute zero) - resulting in an indeterminant value (1/0). However, since this is indeterminant I believe (from my limited understanding) you could use l'hopital's rule to approximate it using the derivative of 1/V, which is 0/1 or 0 - showing that as V tends to 0, 1/V does indeed also tend to 0. Also, just so u know, when you've got some indeterminant fraction like that - you can't simply just multiply through by the denominator, as you end up with nonsensical results like you have shown (1=0)

[@olimaltby5242]

@@thomas4073 you cant use l’hôpitals as the numberator and denominator don’t both tend to 0 or infinity, however it’s fair to say the volume/pressure tends to 0 at absolute 0, the same way we cannot reach absolute 0, just get very close

[@talalabughazaleh4922]

so underrated

[@ayomide3238]

for Boyles Law How does the force from masses cause a decrease in when your are increases amount of masses?

[@maxherbert8382]

because as pressure increases the value of 101kpa - applied pressure gets smaller as mass increases

[@masonfuller7848]

on the first one, why is the change in pressure equal to the pressure its currently under take away the pressure added from the weight? i thought the pressure from the weight would be the change in pressure?

[@drb6740]

the pressure from the air is pushing the syringe up (101Kpa) and the pressure from weight is pulling the syringe down (e.g. 9kpa), so the resultant pressure of the gas is (101-9)=92kpa

[@masonfuller7848]

@@drb6740 oh so it’s actually the overall pressure after you have taken the value of the weight away? Not the overall decrease

[@diajk.1769]

Are these required for ocr phys

[@liamfinley723]

Do you think they will ask about the practical for pressure law on paper 3?

[@arthurguest7432]

i doubt it cos on pmt the required practical only talks about boyles and charles

[@NoahAllouane]

You are a god among men special place in heaven for you☺️ just cheated wackers ta

[@samuel3176]

For boules law he didn’t explain the 100g-1000g. I don’t get it’s value

[@ScienceShorts]

Add 100g to 1000g of mass on the bottom to change force.

[@samuel3176]

@@ScienceShorts oh thank you so much

Risk assessment bro

Hot stuff makes skin ouchy

[@karenspencer8089]

Actually you can write Charles' and Charles's www.lexico.com/en/definition/charles'_law . Otherwise, great video, good revision tool for my eldest daughter Jessica. Karen x.

[@ScienceShorts]

The written word always follows the spoken word. We don't say "Charles law", we say "Charleses law". We say "peoples" - there is no extra 's' for plural possessives. I guess I would argue that just because something is accepted doesn't mean it follows literary rules or norms (if there are such things ultimately...).
Glad you found the video helpful!
