Aw, thanks!

Have to agree here

Thank god for advanced information

Did you pass?

very insightful thanks, shmuckthenonce lmao

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

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

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)

@@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

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

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

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

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

@@ScienceShorts oh thank you so much

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!
