You're videos really are excellent. I'm using them almost exclusively for my classes while we're home learning. I plan to keep using them once normality resumes. I hope you're seeing an uptake in views and subscribers!
You all prolly dont care but does anyone know a trick to log back into an Instagram account..? I was stupid forgot the account password. I love any assistance you can offer me.
@@iya4631 I’d love to be a cardiologist lol- taking maths, bio and chem at a level rn it’s going well I think, wbu? What do u wanna be?? Also tysm for the congrats 😭
How does this person explain the concept in five minutes when my physics teacher couldn't do it in 100 minutes?!?!?!?!?!????? This is incredible hahaha
THIS GUY HAS PUT ME IN SO MUCH CONFUSSION!!! In 1:16 He says that temperature is a "measure of the average internal energy of a substance" and this is WRONG. Temperature is apparently the measure of only the average kinetic energy!!!
did you watch the video? he literally says internal energy is either potential energy stores but since this video is abt thermal energy internal energy is kinetic energy store in a substance
some misconceptions I think: temperature is proportional to THERMAL energy, not INTERNAL energy (which includes the potential energy stores of the particles too)
Some Pople go for the complex looking videos because they think they will become super scientists when what they actually need is a 5 mins video which explains all they need while saving time.
Your videos Are really helpful But could you please add more practice Questions and it would be better if its from a past exam paper . I would really appreciate it
00:05 Internal energy relates to temperature using specific heat capacity 00:39 Heating a substance increases its internal energy. 01:13 Internal energy determines temperature 01:48 Specific heat capacity measures energy needed for temperature change 02:22 Internal energy equals mass times specific heat capacity times change in temperature 02:56 Calculating change in temperature using specific heat capacity of water 03:32 Converting energy units and calculating final temperature change. 04:04 Energy loss to surroundings affects temperature change
@@AayushChitnis it obviously did Mae sense bc everyone else is learning from it ur just a pessimist who thinks he's cool bc his opinion differs to everyone else's even if its wrong

TH-cam is indeed a very good place to learn !
1:12 1:13 1:14 1:14 1:14 1:14 1:14
you literally saved me thank you so much a 4 minute video explained even more than 1 hour of the teacher explaining only one page
Really happy you found it helpful!
JESUS LOVES YOU HE DIED FOR YOU!! CHRIST IS COMING PLEASE REPENT BEFORE IT’S TOO LATE!! :((

@@brodiegianni235 you can reset password using the phone number or email address lol its a bit late
do u think normality has resumed?
I've been watching Cognito ever since i started doing igcse and it was really helpful. Keep up the good work!!. love ur vids
btw i subscribed you deserve prob like 1 millions subs or so
This man saves me in all my science tests
ikr
I like the pracitice questions at the end they are pretty useful
same

These short vids are SOOO HELPFUL 💯❤️
very epic helpful video, helps me forget about my parents divorce
big poggers!
kekw
That is Epic my Guy!!! Fat Pog in The chat!!

Oof
lul
I remember watching this man during my first mock. I had 4s in all of em. Not skip to the last mock (second mock) I hit 7s in all of them
OMG CONGRATULATIONS WOOHOOO what do you wanna be?
@@iya4631 I’d love to be a cardiologist lol- taking maths, bio and chem at a level rn it’s going well I think, wbu? What do u wanna be?? Also tysm for the congrats 😭
amazing, great scores!
BEST EXPLANATION EVER IN THE ENTIRE WORLD YOU DESERVE A ❇
You are a life saver! Helped me to pass my exams and saved me from beatings 😅.
How does this person explain the concept in five minutes when my physics teacher couldn't do it in 100 minutes?!?!?!?!?!????? This is incredible hahaha
Are you going to keep uploading videos, Cognito? These videos are brilliant!
That's the plan!
your videos literally Sade my life, thank you so much
Thanks Rawan, glad to hear you're enjoying them 😊
This channel must reach 1M subs
Have an exam next week bro.. u saved me!!!
This is the best youtube chanel for learning thank you 🙏🙏🙏🙏🙏🙏

This channel is amazing explains everything so clearly my teacher should take notes from here

Thanks Cognito!!! Great for a year 10 student ❤
I love this video! amazing work!
the fact that no one in the world can understand these topics in school , tbh we all get passed in exams by these videos
정말 감사합니다. 동영상이 마음에 들고 도움이 많이 되네요.
Ur a life saver my bredren
you just saved my for my test😭
My teacher recommended this, hopefully it helps me not fail physics
So useful for my mocks!
Youre actually the goat man
What do you mean by system? 0:25
I think he means an object or group of objects
Go watch video
Glad to know , I'm not the only one who didn't got it :''-)
@@GamerJayden49 isn't that what a "system" is in this context?
Its not often that you see a channel where every comment is praising them
very helpful thank you
4:36 Is Soo good times I like YOUR work
Can you do a video on resistance and IV characteristics?
Hi Jannel - take a look at our physics playlist there’s video covering resistance and voltage calculation in different circumstances :)
I really need this and btw I subscribed
Some Pople go for the complex looking videos because they think they will become super scientists when what they actually need is a 5 mins video which explains all they need while saving time.
bro is out here savin lives. W Cognito
Thx soooo helpful!
You’re so welcome! Thanks for taking the time to leave us a comment 🙌
Your videos Are really helpful But could you please add more practice Questions and it would be better if its from a past exam paper . I would really appreciate it
he has practice questions and past tests on his website, he can't add more to his vids coz then they would be too long
thank you for this great video, it's been very helpful :)
You're very welcome!
thank you so much for your awesome work!!
cul vid dude really helped like big time
Bro u have my respect❤
00:05 Internal energy relates to temperature using specific heat capacity
00:39 Heating a substance increases its internal energy.
01:13 Internal energy determines temperature
01:48 Specific heat capacity measures energy needed for temperature change
02:22 Internal energy equals mass times specific heat capacity times change in temperature
02:56 Calculating change in temperature using specific heat capacity of water
03:32 Converting energy units and calculating final temperature change.
04:04 Energy loss to surroundings affects temperature change
1:54 Is it always have to be 1kg? Can i write 1 gram in the test?
no
No bcz this is the formula and it refers to 1kg specifically and there is a lot of difference between I kg and I g
Not really, unless you write your specific heat capacity as ____ J/g (degrees) it would be incorrect
why does the substance of specific heat capacity may give value greater than the actual value?
im confused on this bit 3:12 because I have done 0.8 x 4200 = 3360, then I divided 3360 by 20,000 which give me 0.168 not 5.95??
the formula is E/mc so it will be 20,000J/(0.8kgx4200𝑱/(𝑲𝒈 ℃) which will be 5.95. its not 3360/20 000 ok
i love this video its amazing bbc!!!
Literally all topics of my textbook are covered in these vids
i actually love u sm
You saved my life I have a science final test is tomorrow
Needs more subscribeers
Can you explain internal energy using an example question
0625/22/f/m/18 question 11
thanks for this video
Me 1 hour before exam:
How would you explain this to a third grader ?
wtf is a third grader doing with specific heat capacity
These people are carrying science on there back
Thank you once more
excellent
thank you ya haywaan
can someone please tell me if this video is enough to get a grade 9
I didn't understand the example
Me too
Thanks❤
Do you get paid for this?
His channel is monetised, not sure if hes an individual running the channel or a company
thank you
Best video ever watched😂
Ppl who disliked this r jealous that they're not as smart as him
This video made no sense
@@AayushChitnis why are you watching it damn hate comments even in learning videos
I did not dislike the video I’m giving my honest opinion not sugarcoating it
@@AayushChitnis ok who cares
@@AayushChitnis it obviously did Mae sense bc everyone else is learning from it ur just a pessimist who thinks he's cool bc his opinion differs to everyone else's even if its wrong
congratulations you received
1:30 NICEEE
Mantap!
Never hesitate to use your energy in physics. 🔬🥼🔭🧪⚛⚛
why is there one dislike
W bro
Please be my teacher 🙏
👍
damn some of these coments remind me of covid life
I wanted to like but it’s at 420
Fucksake i still cant fucking understand mate
ok then what do you want me to "do clap"
I am in school
Pin me pls :)
Pog
Yukiko pfp
pog 😌
Can u pls make it funnier videos not just giving information
do you even go to school cuz learning isn't meant to be fun ☺️
@@arandomweeb6143 fr this guys definitely set 8
uhh it's not his job to create funny educational videos, just educational ones.
so do I add the temp change into original and that's the change in internal energy? I wouldn't do 0.8x4200x5.95?
So useful for my mocks!
