Yall legit saved my science ngl.. taught me more than my teachers good job

cognito you're literally the reason im passing my olevels now tysm lifesaver

*My teachers sometimes put this on for us and it’s actually really helpful to understand the topic :,) helping for revision for my Physics exam today 😂*

Thank you so much!! I have my exams tomorrow and after reading the books and listening to the teachers I still couldn't understand this properly but your video made everything crystal clear!!! This is simply an AMAZING explanation. I will make sure all my friends subscribe this channel 🙏

This taught me more than 2 weeks of listening to my teacher did THANKS COGNITO !!!!

u are carrying my science and maths gcse course, this is better than a tutor ngl

Thank you for making this!! My textbook totally glossed over all this and simply mentioned “latent heat” I was curious to know more

Thank you, I've had struggles with this topic for a long time but now its completely solved

Bro your videos are really good. I have watched many topics from your channel and i understood them like never before! Tysm! 😊😊

Please keep making videos i find them really helpful for revising over topics i don't understand very well

0:23 "We also saw that temperature is just a measure of the average internal energy of all the particles..." misconception: it should be "average kinetic energy" Internal energy is a property of bulk materials, not particles, and is defined as the sum of the total potential energy of all the particles plus the total kinetic energy of all the particles.

dude, you are awesome, please continue

this is the best explanation Ive ever heard

thanks you made my studying way easier

the graph is so beautiful sir, thank you for your video

This video is so simple and very helpful, thanks!

Amazing Video! You guys deserve more views! I hope it happens asap❤️ All the Best🌼

thank you so much, i went to the toilet while my teacher was covering this and missed out on this. my science test wheter im in normal science or triple science is coming up and this video really helped

Thank you, thank you, thank you.

1:20 "And remember that the temperature is just a measure of the average internal energy of the particles...". Sorry, wrong again. Temperature is a measure of the average KINETIC energy of the particles **not internal energy, kinetic energy

I say remember the equation by 'email' because E=MxL

Sir you are the best. ❤❤❤😊😊

Awesome. Thank you so much. 👏👏👍👍

You are very helpful in teaching tysm! :)

Can you please make the practice questions and past papers on your website a lot harder, or provide harder alternatives because I find your videos packed with dense information that I find really helpful in difficult exams but the practice questions and past papers are relatively easy and I don't find them challenging. Thanks, and I love your content!

Hi, Thanks so much for your resources - I was using this in class today and noticed you define temperature as a measure of the average internal energy of the particles. Unless I am confused, I believe the temperature is a measure of the average kinetic energy of the particles in a system - not including the potential energy. Without this distinction, it's difficult to explain how energy is conserved during the process (i.e. the energy is transferred to potential energy in the particles, instead of kinetic energy?). Interested to hear your thoughts and justification either way! :) Thanks again!

U explain better than my physic teacher ngl thanks

Hello, so if we want to know the energy required to change ice to gaz we have to use as L : 2 220 000 + 334 000 ? Thanks for the videos by the way, they are very well explained and well made ! You deserve much more views

Really nice 👍

which app did you use to edit this video?❤❤💛🧡💚💙💜🖤

I appreciate your handwriting.

Thanks a ton for mentioning the education board syllabus! I was trying hard to think about this topic but later I realized- There's no topic of this in IGCSE!😃🔍

Thank you mr amr!

Hi a doubt , will the internal energy still increasing during the Vapourisation/ Fusion states?

many thanks to you sir

That's my revision done

thank you very much sir

Please continue to make videos :)

1:17 "Rather than increasing the particles' internal energy" - sorry, this is wrong. The internal energy IS increasing during a change of state because although the total potential energy of the particles is increasing, even though their total kinetic energy is not increasing. Internal energy = the sum of (total PE of the particles) and (total KE of the particles)

Do you do ocr gateaway exam board

ilysm .

thank you !!!!!

THANKS

amazing

You sound like one of my friends at school

AMAZING! everything I needed, thank you p.s I’m boiling hot I think my heating is too high, well I better get ready to use the relevant VAPORISATION data from the table 😂

1:17 I thought the internal energy still increases during a change in state because the potential energy is increasing (even if the kinetic energy isn't)

thank u soooo muchhhhh im acc crying i was so stressed because i didn't understand it at all but finally i do thank u soooo muchhhhh :)))))))))))))))))))))))))))))))))))))))))))))))))))

I get so many hw from you by my teacher

Good❤

how did you create such video? what kind of software did you use?

trés bien

Shoutout to cognito

1:19 Do you have birds?

bro what? 3 pages of notes in 6 minutes holy fuck

weeeeeeee

Hallo 🤚

only 933 likes??? seriously???? smh...

Ueu

Hey Great Video and very helpful, can i know thw name of the app that gives you the whiteboard and the font and if it is not an app please explain😍

how could anyone dislike if u do u sad boi

this is the most boring thing I've had to watch

I have gcse mcq paper 1 after 1 day and bro I want to thank you for all the help throughout my O-levels 2021 - 2024 ..3 years... Finally I say honors to all the memories of watching ur videos late night stressed af n all ..☝🏻🫡
