Man here we're on a distance learning system due to the pandemic. The learning modules given to us is quite hard to understand without someone teaching it. Luckily I found this video and it was a great help. Thank you.
I can not even believe it!!! I have been in class for 1 week totaling 3.5 hours and THIS VIDEO summed up in 5 MINUTES what my professor has taken 1 week to poorly explain. College professors teaching in classrooms are a dying breed! WHY do I have to go to class? WHY? It is ONLY so the professors can draw an income. I feel bad for THEM, but they are a waste of time and effort.

You quickly went over something here regarding the significant digits in rounding up/down your answer. Could you do a video (if you haven't already) discussing this? In all my years of science learning, I've never had the training on how to deal with measurements and the ± margin of errors and such. My college chem assumed we learned it somewhere. The college physics, well, everything was either 0, 1, π, e, or √2. For example, you weigh an object on a scale with accuracy of ±1gm, and you measure the dimensions of the object (say, a cube) with accuracy of ±1mm. What is the density of the object and what is the accuracy of that calculation?
You're in luck! We have made a video about significant digits: bit.ly/Sig_Figs We also did one on scientific notation (another problem area for a lot of people): bit.ly/Sci_Notat Thanks for watching! 💜🦉
I've been trying to understand Boyle's Law for years now and this has really helped me but I do have a question. In the first example, the answer was 47.36, it wasn't rounded up to 47.40, yet in the second example, 10 divided by 3.5 equals 2.85 and it was rounded up to 2.9. Could you please explain why this is? Thank you!
+Crisse Romero Good question! You can only use Boyle's Law when the temperature is constant. If it doesn't appear anywhere in your problem, you can assume it is constant. If temperature *is* changing, then you would use one of the other gas laws that involves temperature (Charles's Law relates temperature and volume; Gay-Lussac's Law relates temperature and pressure; the combined gas law uses all 3 temp, volume, and pressure). Thanks for watching! :)
But in constant temperature the molecules have same kinetic energy. So why pressure is increased if in every small surface of the container the same force is exerted?
tell me why my calc is saying 2.8ccs I don't know which to believe... no seriously tell me and one more question how do we know that taking the given on p2v2 and divide it on both sides gives us the correct answer? note: this is a serious question I suck at math like really suck at math and just got interested now so any answer will be greatly appreciated

Guys why are u not making any videos like this you guys are experted in explaining there is a lot of demad for video of che ,maths and physics in India due to iit apirents in India if u make other videos on topic like this and organize it your chanal will be in a good position .. don't mind just said due to curiosity ...

TONS of information there, including links to related videos and recommended reading. Thank you for watching!! 💜🦉
+Charens Luo It's to get P2 (the new pressure) on a side by itself. You could instead do the dividing before you substitute in any values - that is, start with P1V1 = P2V2, and divide both sides by V2, to get P2 all by itself. Then plug in the values from the problem to get the numerical answer for P2. Thanks for watching and commenting! :)
We would love it if you would share a link to the video with your friends! That really helps us grow - which means we can keep making more videos! Here's a link to share: bit.ly/Boyles_Law
Thank you for posting this video. One question, why use psi instead of Pascals? You are using liters for volume, so I would have expected SI throughout.
Thanks for watching, Pascal Chesnais! We used psi for that example because here in the US, most of the time recommended tire pressures are measured in psi. And for air pressure, we commonly use atm or inches of mercury (instead of mm Hg)! It's a bit of a mess. If only we would go metric and/or SI. One day...

Oh boy ! It reminded me long time ago. Thanks
thanx for the info
Thankyou so much.
this saved my chemistry mark
Why can't my teachers just be this goooood😭😭
Trevis Schiffer this video took 5 minutes to explain something perfectly understandably, I think these teachers can do better.
@Trevis Schiffer I agree with you.
Even good teachers lose their focus in that pressure.
Trevis Schiffer yeah, you’re right. I might’ve been a little insensitive to teachers.
Same here

I love how her voice didn't changed that much lol. I wish I could speak this smoothly while presenting in our class. Thanks for this!
Learnt more in this short video then 2 weeks of school

why do teacher don't explain this with ilustrative images? I think it will be way simple to understand the law
Thanks...we really need teachers like these in my school

It's actually 2.856 which, when rounded off, gives 2.9
Hey! are there only videos in the official website or is there any study material too??
really good video let's continue like this
How do you know which PV divide to
Do a video on Pascal's Law.
Naice
Rajkumar Rajj nice*
Where r u from?
someone knows how to do powerpoint like this?
i need answer please
what happens when you increass the temperature or change what should remain constant
how do we know what to round to?
So helpful... Thank you Madame 👏🏽
So informative! Thank u!!
Best visualizing teaching
Awesome. Concise. Clear.
Y jo V2 ka answer araha hai wo ksy araha hai or usko kya multiply kr rhy hai y divide plzz btae
So, pressure means INTERNAL pressure of the gas, not EXTERNAL APPLIED PRESSURE,
is that right...?
Is it not based on absolute pressures?
uhm hey, what if the temperature is missing?how do I solve for that?
+Crisse Romero Good question! You can only use Boyle's Law when the temperature is constant. If it doesn't appear anywhere in your problem, you can assume it is constant. If temperature *is* changing, then you would use one of the other gas laws that involves temperature (Charles's Law relates temperature and volume; Gay-Lussac's Law relates temperature and pressure; the combined gas law uses all 3 temp, volume, and pressure).

+Socratica im actually good 😂 i also realized that when our teacher discussed it. thanks btw 👍😄
Crisse Romero awesome, good to hear. Let us know if there's more chem topics you'd like to see. :)
sure I will. Thanks :D
When the volume gets smaller and the molecules get closer do the molecules change their state of matter?
If the gases are at a temperature lower than a certain "critical temperature", then yes, increasing pressure will make the gases liquify.
Great content, learning this for my sealed system refrigeration training. Thank you!
Why do u divide by 10.6 On both sides?plz explain
I dont have words . this is more than best
Great video!
very nice explanation i understood it very easily
Thank you for this!
You are so welcome! We're so glad when we hear our videos are helpful. 💜🦉
But in constant temperature the molecules have same kinetic energy. So why pressure is increased if in every small surface of the container the same force is exerted?
How can I solve for V1?
44 psig = 58.5 psia
58.5*11.41 = P2*10.6
P2 = (58.5*11.41)/10.6
P2 = 63 psia = 48.5 psig
Thank you so much......It helped me a lot...
I love this im even starting to love the topic
the explanation is really tremendous.
i have a question, why cant I just write P/V? so when pressure goes up, volume goes down and vice versa. or something like this ↑P1xV1=P2x↓V2
tell me why my calc is saying 2.8ccs I don't know which to believe... no seriously tell me
and one more question how do we know that taking the given on p2v2 and divide it on both sides gives us the correct answer?
note: this is a serious question I suck at math like really suck at math and just got interested now so any answer will be greatly appreciated
It's really helpful
so clear! very good video.

If volume is increasing than the pressure is decrease and when volume is decrease than the pressure is increasing so how temperature is constant
OMG finally I get it.....5 different vids later. Thankyou!!!
Thanks this was a great explanation
I cant belive theres NO videos in all youtube that can explain HOW much volume of air increases per 1 additional psi
Thank you so much I learned a lot in you vid
I appreciated this video, this help alot😅.
