To see all my Chemistry videos, check out socratic.org/ch... Reviews kinetic energy and phases of matter, and explains the kinetic-molecular theory of gases.
Will this be the right answer to the question: What is an ideal gas- There are a set of expectations or rules that come under the kinetic molecular theory and when a gas follows all of these rules then it is called an ideal gas Is that answer good in terms of use in scientific vocabulary etc?
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Just know that you have saved my chemistry grade. I have a first year teacher and they have not yet grapsed how to break chemistry down for us to understand it. You have done a great job. Thank you
your passion, communication, drive and patience to name a few things makes you the ideal teacher, someone whom both current and future generations of teachers should aspire to become. Thank you for everything you do! there isn't a single person who has watched even a second of your videos who did not leave having gained from your videos :)
Are you still making video ? You’re a great teacher . Your video absolutely helped a lot of people. I love the way you explain hard concept, your unique way to explain chemistry make chemistry so much easier!
Hi, Tyler I am struggling with chemistry. love your channel and was wondering if you give tutoring sessions? I am in Elementary Chemistry 101 and currently in chapter 12 The Gaseous State of Matter.
An important clarification: in a collision, kinetic energy becomes a different kind of energy (rather than disappearing). Like matter, energy must be conserved. Thank you for the video, it was super helpful.
You are really amazing ! Your methods and teaching style are delightful . You make it easy to fall in love with this energydraining subject ! Wish ya all the best !
wish i had teachers like this at school... think you are doing a great job mr dewitt, please keep it up. and I want to ask whether I can get permission to download your videos and teach some children using 'em...
thnxu sOo much 4 posting the video!! I wish u were my chemistry teacher ... :) .. excellent wrk .. :) .. now I dont have to read 6 pages of my textbook .. :):)
I have a question, if gasses bounce around in a container and their collisions are elastic, then can this behavior also be true for solids and liquids too? Although the only difference I see is that liquids and solids are held together by molecular forces- is this correct? Else would they too (liquids and solids) be freely bouncing in a container?
That's correct. Liquids and solids have significant intermolecular forces that maintain their size and shape. The molecules are still bouncing around, it's just that the intermolecular forces restrict the total amplitude of that bouncing around (in the case of a solid) to be confined to the crystal lattice. In the case of a liquid, the molecules can move past each other, but don't have nearly as long of a mean free path as they do in gasses, and are confined to maintain the substance's volume, but not its shape.
Water pressure, gas pressure, air pressure.....X-body pressure... Well, which way is the direction of such pressures, what is the effect of all pressures on pressure receivers???//
2:31 Doesn't the KMT assume that the particles don't collide with one another? It says here 'Particles don't exert a force on one another.' Doesn't this mean they don't collide? A collision involves dp/dt=F, which means a force is exerted in any collision.
KMT assumes that intermolecular forces ONLY happen at the instant that the gas molecules collide. Once the gas molecules are separated, KMT assumes there are no forces between them, or the walls of the container. The collisions are also approximated as instantaneous, such that the impulses are brief.
it was really a dazzing video tyler...u r really helpful a lot....but I am searching for ur videos particularly on chemical kinetics wholly...but i couldn't get it...can u plz help me?...I am preparing fr an entrance scam...that's y
I've been searching... I can not seem to find information on specific gasses. Just general information. In a nut shell this is my question. If I put 500ml of liquid (nitrogen or hydrogen or oxygen) in a 40 Cu/ft. gas cylinder and allowed it to warm up to 22.2°C , how much pressure would be in the cylinder? Where can I find the base information to do the calculations?
Nonsense, or perhaps you do not understand the question. Water is a liquid, heated it becomes a gas (steam) that creates pressure. one gallon of water in a 5 gallon container heated to 360° will produce 160psi. Liquid nitrogen heated becomes a gas...
@@MrTHEORIGINALICEMAN Given: 500 mL of liquid nitrogen 40 ft^3 = 1132.7 liters of container volume Assuming the remainder of the container is air at 1 bar & 22.2 C at the instant we seal the container, we can determine the final pressure of the container after the liquid nitrogen boils. Air's effective molar mass of 28.97 grams/mole, which is a standard value you can look up, or calculate from air's composition. Strategy: 1. Find the mass of air and nitrogen in the container. 2. Find the corresponding number of moles of each 3. From the total number of moles of the above, the known container volume, and known final temperature We can look up the density of liquid nitrogen at its 1-bar condensation point, and that is 0.8071 g/mL. From the ideal gas law, air has a density of 1.18 kg/m^3, or 0.0018 g/mL. 500 mL of N2 liquid is 403.6 g. The remaining volume, 1132.2 Liters of air, is 1.336 kg. Divide by molar masses (28 g/mol for N2, 28.97 g/mol for air) to find number of molecules. N_air=46.1 mol N_N2=14.41 mol N_total = 60.51 mol Use the ideal gas law, solve for P: P = N*R*T/V Plug in: V=1132.7 L, N = 60.51 mol, R=8.314 kPa-L/mole-K, T=295.35 K Result: P = 131.2 kPa
Wow! 2022 and still very helpful for the new gen chem students. Thank you sir!
i hope to get one up here soon. but in the mean time, feel free to message me if you have questions. i appreciate your kind comments--they mean a lot!
Your videos are going to be the reason I pass my Chem final tomorrow.

One of the most underrated educational channels ever. Keep it up
Arnold Miao how is he underrated? all of my friends use Him to save our grades haha. hes a lifesavr
Your videos are still saving people 10 years later! Seriously so thankful I found your videos :)

You are a great teacher. Explaining things in a way my college professor just can't accomplish. Thank you so much please keep it up!
Tyler, I'm taking my chemistry final exam in a few days. This video is INCREDIBLY helpful, thank you so much! You did an awesome job.
you are the best chemistry teacher who knows how to explain the chemistry
thanks a lot
@sfincher100 congratulations! i'm so happy to hear that!
The fact that some people(usually 1or 2) dislike your videos is a JOCK. God bless you bro.
bro you are goated carrying me through chem
Thanks Tyler for all the videos you have done that helped me understand Chemistry for my nursing degree.
best chem teacher award goes to: Tyler DeWitt!!!
Tomorrow is my Chem final, and you are saving my life even in 2022
thanks your videos helped me pass grade 11 chemistry. they are very helpful 👌
This guy made me fall in love with chemistry
Are you still making video ? You’re a great teacher . Your video absolutely helped a lot of people. I love the way you explain hard concept, your unique way to explain chemistry make chemistry so much easier!
There is always a smile on my face when I search a lecture and I see Tyler on the page
Hi, Tyler I am struggling with chemistry. love your channel and was wondering if you give tutoring sessions? I am in Elementary Chemistry 101 and currently in chapter 12 The Gaseous State of Matter.
A lot scarier than it sounds lol
Lol
Thats how I feel about all chemistry xd
A lot of things can sound scary, especially if your camping out in the woods by yourself.
Thank you Tyler!!!!!! This was my favourite in the 'Gas' unit. No one could have explained it better 😊
watching this in 2020, Tyler is the best chemistry teacher!
"Which is a lot scarier than it sounds" lmao
An important clarification: in a collision, kinetic energy becomes a different kind of energy (rather than disappearing). Like matter, energy must be conserved.
Thank you for the video, it was super helpful.
İ'm from Turkey.I can understand clearly only from your videos.Thanks❤❤❤
you are literally so amazing and you explain stuff in such a way that just CLICKS with me--I love you!!!!
Helping out since 2007. It feels sad to see still under 1m subscribers.... But Best wishes Mr. DeWitt. Honor.
You are really amazing ! Your methods and teaching style are delightful . You make it easy to fall in love with this energydraining subject ! Wish ya all the best !
This man deserves better! Road to 1M subs!!!!
youve helped me so much with chemistry man haha im passing chemistry because of u
You Help Me Pass My Chemistry Tests And Exam :)
At 0:18, did you mean, "Sounds a lot scarier than it is"?
no, because at the atomic level, there's some pretty scary shit going on, which makes it scarier than it sounds.
You're amazing please create more videos. I am a huge fan and subscribed. You are very good at explaining things. :-)
Mercedes Malone lol
I would sell my soul to have this guy as my chemistry teacher
wish i had teachers like this at school... think you are doing a great job mr dewitt, please keep it up. and I want to ask whether I can get permission to download your videos and teach some children using 'em...
Thank you for your videos! Studying for chem is a lot easier when you understand what's going on and you've explained it so well!! HUG N KISSES!!
i wish u were my professor....thanks
the best ever explanations...thank you sir
you are so freakin awesome i love the way you explain things so thoroughly
When I become a teacher I'll just seat back, eat doughnuts and play your videos for my learners
This video was so helpful I regret going to a tutor lol
Here we see a younger Tyler, still extremely helpful but not in as good of video quality as now.
you're a fabulous teacher!!!
Who else is watching his old videos in 2022
Me!
you're there best explaining science.
thnxu sOo much 4 posting the video!!
I wish u were my chemistry teacher ... :) ..
excellent wrk .. :) .. now I dont have to read 6 pages of my textbook .. :):)
This vedeo is saving us after 14 years
Really helpful, thanks, gcse physics just got a lot better :D
Hey!!! you are the most amazing teacher!! Thank you so much and it was a lot of help. Thanks!!! Thanks!!
ha! i'm waiting for you to make that one.
the momentum is conserved in ineleastic collision and elastic collision
2024 and and still helpful
Is there something wrong with the volume in this video -_- I've raised my volume all the way up and I can barely hear you...
Tyler DeWitt- Getting me through my Chem exams since 2018
Very good explaination sir thank you so much
Which way is gas moving to have a kinetic force or energy? which way is acting the force of gas or gas pressure?
Thanks.
I wonder how Tyler is doing now? I hope he's happy and living a good life
kindly raise your voice U ARE GREAT TEACHER I LIKE YOUR WAY ALOOT
This was made 12 years ago! :D-thumbs up-
Still helping out in 2023✊✊
my teacher always plays your video and he likes you because he thinks you look like justin bieber 😂✌ true story
When this vedio was uploaded I was 3 years old but now I am 16
i admire you so much..
totally amazing ^_^
i love your works toooo much ..
god bless you

"a lot scarier then it sounds" Nice wording
