GCSE Physics - Conduction, Convection and Radiation #5
ฝัง
- เผยแพร่เมื่อ 20 พ.ค. 2024
- In this video we cover:
- The 3 ways heat energy can be transferred
- How heat is conducted through solids
- What thermal conductivity means
- How convection cycles work
- What radiation is
General info:
- Even if you don’t need to know the details for your course, it's worth watching to understand the concepts
Exam board specific info:
AQA - Everything is relevant to your course!
IGCSE Edexcel - Everything is relevant to your course!
Edexcel - You do not need to know conduction or convection in detail, so you can skip to 4:45
OCR 21st Century - You do not need to know conduction or convection in detail, so you can skip to 4:45
OCR Gateway - Everything is relevant to your course!
Hello everyone! At 3:30 we make an error in the narration. We *should* say: "Because they're less dense, these particles rise above the colder, MORE DENSE particles above them."
As an aside, we'd really love to hear any constructive feedback you may have for this video (and the others!). We spend a lot of time trying to guess what people will find clear/helpful to understand, and which bits are harder to grasp from the videos - we're bound to get it wrong from time to time, and it would really help us to hear which bits work well for you, and which bits work less well :) Many thanks, and wishing you all good luck!
Cognito pls can u answer me quickly if you mix hot water with cold water is heat transferred by conduction or convection
@@odacove9823 Solids is conduction and liquid+gas is convection
In a vacuum like space it is radiation

Oh come on its okay 👌
@@odacove9823 convection as it takes place with fluids
start of the video: burning a calculator
me: oh i love this video already
Lol 😂😂
1 yes 2 love ur pfp and the anime
lol i thought suga loves studying haha
Akward😐😳
@@jbsjdbsibja9441 nah it’s just for show 😌
I have a science test about Convection, Conduction, and Radiation TOMORROW and this helped me a lot! Thank you so much!
Hey thank you for the comment! Really happy to hear this helped you :) good luck with all your work!
Azek Clapzz did you do good on the test?
@abdullah iftikhar Okay, you can stop bragging.
@abdullah iftikhar Its "video" btw not vidio.
@abdullah iftikhar Well, your making a little too much mistakes dude.
My teacher took around two weeks to explain this and you did it in 5 minutes. Thank you so much
Same here
same here xx
an entire month for me
cognito is worst course that i see never in my life science hazard always is best lets go sceience with hazard
brooo, same shit happened with me, she took 4 lessons (2 weeks) to explain this, and i didnt understand her, but cognito rlly helped alot
I'm doing some last minute revision before my physics paper 2 tomorrow, and I just wanted to say a huge thank you! I honestly cannot thank you enough for all of your help. I discovered your channel about a year ago, when I was really struggling with physics- my teacher wasn't the best, and I was stuck on 6s and 7s. When I started watching these videos, I genuinely felt like something clicked in my mind, you explain things in such a logical way, and I love the interactive animations! Before long, I was getting solid 9s in my mocks, and I can safely say that it is down to you. You have made so many difficult concepts make sense, and have alleviated all of my worries for science. Thank you so much Cognito, I hope you realise how much positive impact you have! You have transformed me, and so many other peoples' learning, and made it such a fun and enjoyable experience.
In which grade are you studying? Grade 9 IGCSE?
@@chinmayeesaikia6507 yes
same story
Like 80% of these views have been from coronavirus online learning
LOL YEAH or just tests
True
True x10
Looooool yhh
Yup
i never quite preferred learning online, but exams are near and somehow i need to ace it and ngl found a perfect youtuber for it 😅✌🏻✨ (p.s. its so wonderful learning all those awful chapters for hours into just a few minutes video)
Put your hand if ur in 2023 and your watching it to support you in your test so you don't struggle ✋
Yeah I'm using it for exam I'm in ss1
Same
Yes
This is my first best educational channel. Because of this channel, i understood everything and now its easy for me. Thank you so much.🙏🙏🙏🙏
thank you sir
you just “transferred knowledge” to me in a process known as video teaching
thank you so much once again
👏👏👏
I have a Physics test on Heat and temperature tomorrow, this helped me so much! Great explaining btw.
you explained this 10 times better than my cgp textbook did after two hours of reading it and still barely understanding anything. thankyou so much your gcse series courses are very helpfull. they are so well explained and easy to understand
Great to hear you found it useful - thanks!
this helped me ALOT thank you very much Cognito, literally anything i need to use for physics, chemistry, math and biology is all here. Thank you and this helped me alot.
Who else is watching this from your teacher cuz corona?
redanaxle _ 😗✌️
Me
Yup
your mom
Me
Better explanation than my 40 year old physics teacher
I haven’t seen anyone that perfect is teaching, ur a goat
Thank you so, so much! This really cleared things up! Great work!
This is really helpful. I can revise for my online chemistry and physics assessment.
Before watching this video, I was mainly confused about how convection works on liquids but now everything is clear.
TYSM!! I have a physics test tomorrow about this topic and I didn't quite understand but after watching this video my understanding got better!
this was so helpful thank you so much!!!!!!!! i love the style and how clear it is to understand, amazing job!
Thank you! 🙌
Three years later graduated
Thank you! This helped me for my JISMO competition at the end of this month!
my God bless you with everything, I had no idea about it until this video. Many thanks!
I have my finals tomorrow and this helped so much, I was unable to understand thermal physics but this video made me understand it in a few minutes. Thanks! Keep up the good work.
Me same
I think you could include more IGCSE style question on the topic after each video!
This helped me a lot bc we are having a test today and I also have a b+ thank you so much for making this❤️❤️❤️👍👍
u proud of b+? Like srsly?? LOL XD Then you are one of those bad students XDD!
@@spndons. and you're one of those unkind, disliked and bigheaded students who can't help but be mean about someone.
@@sanunstudios Hell yea, so what's your problem you "b+" man??!!
@@spndons. at least they don’t use XD every two seconds go get a life
@@saz8610 Do you even know the freaking meaning of "Xd"... And BTW pls don't disturb me so much I'm on a good mood, burh, I have a nice life, that has nothing but enjoyment. I don't even care about your cringe life bruhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
You literally taught better then my physics teacher and I cleared my concept that my physics teacher couldn’t make me clear in a whole year
28 seconds in and I learnt something that my teachers would probably never tell me but eventually find it on a test. Thank you, I own you so much
Own*
This video, surely help me in my finals. Thankyou very much🤝🏻, keep on uploading New videos 😊
I learnt a lot and very effectively
Thank you a lot my man
me forgetting about this topic and remembering it on the morning of my gcses
literally 😭
I’m watching this cuz my teacher didn’t explain radiation and I still got an assignment on it
lmao
Thank you so much for this! All of your videos are so helpful and I always have a better understanding of the topic after watching them.
Thanks ARGalaxyGirl, we appreciate it 😊
the best revision site..
thanks for saving my life i have biology and physics exams together. It's helping me a lot to revisee xx
this guy explained to me the topic better than my teacher who took 3 weeks to explain it
Props to you
Thanks! One video and I remember everything now!❤
Thank you!
Please make videos on other GCSE and IGCSE subjects
Your video is awesome.I studied this topic from three teachers but I didn't understand it, you made it so easy to learn and understand . However also discuss
Thermal conductivity depends on:
Cross sectional area
Leanght of solid
Temperature differences between ends
,Also discuss convection current in land and sea breeze and gliding
very nice video.& explained in very simplified way....it helps kids a lot to understand difference between these three..... thanx for sharing......
Who else is watching this video because of online classes due to the Corona Virus :}
same
Mobit the Wingman my gosh yes!
yh me
me!!!!
