Boyle's Law 

Thank you, I really appreciate your kind comment. But getting "dislikes" on my videos has been an important lesson for me. Even if I try to do my best, some people will always dislike what I do. Or sometimes on RU-vid people dislike a video for no reason, just to be hateful. I've learned not to let dislikes get me down. I do what I love, and if others don't like it--tough, too bad for them. I think this is an important philosophy for life in general.

great job! i'm so glad to hear that! thanks for the comment, too!

thanks so much! i love to hear comments like this!

12 years later and I still learned more from this video than in my 2 hour class! Thanks so much for your videos, you rock!

Someone give this guy an award

man you deserve an Oscar for helping students around the world 😂😂 thnks

thanks for your comment! i really appreciate hearing that my videos are helpful. i hope you get an A on your test, and message me if you have any questions this video didn't answer.

You are the best chemistry teacher in the whole world. Thank you so much for helping sir.

This guy has a passion for teaching and explains things well, he goes down to the student's level of understanding to explain the concept. Keep up the good work!

14 years later and this still comes into use. thanks tyler for giving us free!!! videos and helping us out. we appreciate the hell outta you

"if something becomes more expensive, fewer people want to buy it." *(laughs in Apple)*

excellent question! you're very observant! balloons are a tricky example, because they're a little different: when the volume of a balloon goes up, we have to ADD more air (that's why you blow into it). in the examples that i talked about above, we're not adding any air: we have a set amount of gas that we're either squeezing into a smaller area or giving more room to. when you start talking about adding more air to something, to relationship gets a little trickier. does that make sense?

much better than they way they teach us at school

HANDS DOWN THE ONE OF THE BEST TYLERS ON RU-vid, FACTS!!

Someone please give this man an award bc I legit teared up over the fact I finally understand these laws

I'll trade my teacher for you anyday... Tyler you're responsible for my success in Chem

Who’s here during 2020 corona quarantine

to solve for P2, you need to get it by itself. so that means you divide both sides of the equation by V2. so you'll have P2 = (P1 x V1)/V2

I'm convinced he's the lord and savior of my chemistry grade

It's 2020 and you're still helping people (especially through the coronavirus right now) online school sucks

Learned more in these 5 minutes than I did in the 2 days my teacher took to explain this. Thank you soo much

In times of pandemic we only do self study but we can't get and understand that much without the help of others with knowledge regarding this matter. And fortunately I found you here in YT. You taught us very well and clearly. I understand it very much. Thank you.

Studying for MCAT, your videos help a lot. Your a great man Tyler DeWitt

Going into my test tomorrow I really learned how to do this I appreciate it thanks a million man👍🏼

Man I got a 91 on my chem where getting 83 is a complete bless and this is all because of your videos. Also the highest in my class and I hope you help me through my exam for a scholarship grant. Thank you again!

Hes literally the reason why im passing chemistry

My chemistry lecturer today was terrible at explaining this to me, I just couldn't get it, and low and behold one of my favorite channels has me understanding this whole concept. Thank you so much.

Man, these universities and colleges should give you 50% of their tuition fee .

Thanks for the help I wish you were my teacher, my teacher is awful at explaining stuff and you make it very simple

This never gets old. I am a teacher now and still watching this for reference. Thanks man!

I live in South Africa and I have a Science final tomorrow morning, untill this video, I did not understand, now i have it in the bag. You single handedly saved my high school career

gabby, thanks so much for your message. unfortunately, i don't quite understand what your teacher is asking you to. i mean, you've described it very well and it makes sense, but it's pretty much impossible to draw the emission spectrum for an unknown atom. hydorgen is the only atom that people really know. but i want to help you out. message me back and let me know more about your assignment.

oh man i really wish i had you as a teacher. it's as if all my confusion and stress has flown away thank you so much

this video was posted when i was 5 years old. today i am 16, almost 17, and once again YOU SAVED ME FROM FAILING.

I'm passing chemistry over the summer and it's all because of you.

I can't thank you enough for all of your helpful videos. My son comes home everyday clueless about his chemistry homework. We have to watch your videos to figure out how to do his homework. Thank you so much for breaking everything down step by step with visuals!! You have been a godsend.

Why do I find that I learn more on these youtube videos then I do in class.?

I'm from the Philippines and we're studying this now in 10th grade thank youuuuuu 😍😍

It's 11:17, i have wake up for school in 5~ish hours, and i have 8 pages of varying gas laws and topics filled to the brim. Thank you

*_It took me about 2 hours trying to wrap my head around my homework, according to what our teacher thought us. But it took me 5 minutes on this RU-vid video to fully understand everything and answer it faster_* That really says a lot for Philippine school systems. It's always the 5 minute RU-vid videos that help me more.

14 years later and your still helping chemistry students. Thank you!

You made it so much more easier to do and to understand. Thank you

A decade later and Tyler is still helping students around the world!

I just want to say thank you for all your help with all your videos!! You have helped me achieve an A+ in my general chemistry class. Although my class is difficult, you have helped me understand it, and enjoy it rather than hate it🙂👏🏽Thank you soooo sooo much!!

i need this kind of teacher, straightforward and easy to understand

You look so young here thank you for making these videos for so long! You're truly talented at teaching!

15 years later…

Sitting in academic intervention (detention) spending 25 minutes stuck on a single problem. Watches video. Realizes all I had to do was divide both sides by V2 to make the equation equal P... oh the simple things.

This makes so much more sense. I have a horrible teacher that has probably been doing this as long as you have been alive. Thanks for making it understandable

Does anybody know where this dude is at? Btw, thank you for the help! My teacher is a good Chem. teacher I'm just the one not really understanding his use of words plus science ain't my best strength in school, anyways, hope you'll make a new video soon! You are really helping a lot of us!!!

I cant thank you enough dude, these videos are much better than my chem teacher teaching this for an entire WEEK! Thank you for these. 👍👍

I hated chemistry when I was in high school. Now that I'm gonna take the MCAT, I'm actually enjoying this. You the best.

Made in 2008, and still so helpful, thank you!

9 Years ago. old school Tyler DeWitt videos ftw! Thanks for making a challenging subject easy to learn! God Bless!

it's 2020 and my chem teacher sends a video in 240p during quarantine. the future is now

You are like the chem Jesus

You sir are a life saver! Don't know why anyone would've gave this a thumbs down!

I must've looked up more than 13 videos for the most accurate Boyle's law.....I got none but suddenly I see this video and my search ends.....this is gonna be the next place I go for help after school!

Hi Tyler, All your videos are really awesome..!! A new benchmark in teaching..!! Science was fun for me already.. U enhanced it.. Thanks a lot for it. But one problem can you just Sort all your videos which u are uploading topicwise and put them as playlists..?? That would be a great help for all of us out there.. U knw what I search for ur videos n it takes a lot of time..! :/ As I feel good things shud be shared so more n more people shud watch ur videos and shud REALLY ENJOY SCIENCE..!! So please look into this. Thanks a ton once again..

12 years and this man is still helping students like me who have a chemistry test tomorrow

OMG! I WAS SO SCARED THAT I WAS GONNA FAIL THIS 9 WEEKS BECAUSE I DONT HAVE A CLUE WHAT MY TEACHER EVER SAYS! THANK YOU SO MUCH! YOU MAKE IT SEEM SO SIMPLE!

You are the best my friend, you simplify staff, and make students understand.

Oh my gosh. Thank you so much. A lot of my class mates don't understand this and now they will with this video.

Thank you so much! I was WAY too focused on getting the unknown value on the left side of the equation, and getting all of the known values on the right side, making transposing terms a problem in itself. It's amazing how simple problems can be so complicated if you make them to be that way.

i searched Boyles law and when i saw that you had made i video on it i instantly clicked with excitement

you were very young but explained already really good. However in my opinion you improved a lot in explaining from then. Keep up the good work Tyler!

Thank you so much, my chemistry teacher is the worst I've ever had in all my years of schooling, so you are a big help!

Thanks so much! I didn't understand Boyle's law at all before I found this video and now I get it! My home school text book didn't explain it well AT ALL and I'm really working for good grades since this is my fresh man year of high school. I feel really confident for science now☺ Thanks again!

you're so much more better than my chem teacher in school

I am so thankful for all of your videos. I am taking a chemistry class online which is pretty much a self-taught class (we don't even have an assigned book!!) so your video explanations are the ONLY way I am surviving this class. Thanks for making complex material so relatable and easier to understand. You are so immensely helpful!!!!!!

Trust this guy more than my chemistry teacher during highschool

Dude you just saved my ass. I have a test in a few hours and i really couldn't wrap my head around this until watching this video.

1 week of school -> 5 minutes of Tyler Dewitt😂😂😂

BRO YOU JUST HELPED ME CLUTCH UP PHYSICS ILY HOMIE

My science teacher really likes this video and your one on Charles's law... watching this was my homework tonight! thank you so much for making it understandable... you remind me of the khan academy guy.

@Jameses213 it doesn't matter what pressure units you have, the equation works exactly the same way. HOWEVER, both P1 and P2 must have the same units!!! so they can both be kPa, or both be atm, or both mmHg, or whatever. but you CANNOT have P1 be in atm and P2 be in kPa. if both P1 and P2 aren't in the same units, you'll need to convert one so they're the same. i have a video on gas pressure conversions. does that make sense?

where is the more complex video you were referring to

Your video has been really helpful till this day!

My teacher just sent us a PowerPoint and fucked off. When you explained that pressure and volume have an inverse relationship everything clicked and I understand why this equation works. Thank you

you have carried me all throughout college chemistry hahah thank you for existing

its 2019 and chemistry teachers are stilll bad

@laniipop why would you convert to kPa? as long as BOTH pressures are in the SAME units, you're fine. here, they are both in atm. we'd also be OK of they were BOTH in kPa, or mmHg, or anything else. the problem starts when they're in different units. then you would have to convert one so that they're in the same units. but it doesn't matter which pressure units you use, as long as BOTH are the same. make sense?

got a quiz on this that I failed with no prior knowledge of this in ALG 2, thanks for helping me pass the retake man

Its 2020 and this is what I need Thanks alot

Reading the book Ishmael mentioned Boyle's law. You did a very good job of helping me understand this concept. I appreciate your work.

14 years later and still top of the game!

taking chem 10 for summer and WOW its a lot, but you have really really helped me!

The best part is that "LETS SEE IF THIS MAKES SENSE" Thanks a lot yur still helping people in 2024😭

I wish you were my Chemistry teacher, it would make this AP class so much better.

Thank you very very very much .. I don't know what to do without you?

Oh my gosh it took my chemistry teacher almost 2 weeks to teach this (and of coarse I didn't understand it) you just explained this stuff to me in 5:42! By the way I have my final exam tomorrow. Thank you so much!

Short and straight to the point..thank you

14 years later, I still learned more from this video than in my 2 hour class!

You're the reason I passed Chemistry 101. Thank you Tyler 😁

Hi I am a science teacher in the UK and find you RU-vid vids fantastic. You seem able to explain things in a direct and understandable way for the Kids Dr N Millward

I can understand this much more than in school...thumbs up to you bro

Fall 2022 and this is still helpful. Thank you from NYC ❤

This is the best explanation. I finally got it, thanks so much!

dude thanks this is rly helpfull i have a test tomorrow and i think ill pass it cuz of u thanks bud keep up the good work

You're a life(and grade) saver. Honestly, truly.
