Just hats off......... This channel went to the extra mile by not only uploading convenient science videos but also the explaining, the voice, the figures are so easy to watch like the only thing you need to do is to listen once or thrice and boom you get to know what you're looking for. Thanks Cognito💙
I've never expected that a video, which takes barely 5 minutes to watch, could resolve my confusion better than a lengthy hour of studying in a seminar.
Thanks a bunch Sir for making these humongously helpful videos on each and every topic! I just wanted to know whether we should learn to draw these 3D diagrams in our chemistry IGCSE?
How come the melting & boiling points of single molecular substances are dependent on the intermolecular forces not bonds, but the melting & boiling points of giant covalent structures are dependent on the covalent bonds as opposed to intermolecular forces?
Tom and Amadeus, I'm overjoyed to see all the new subscribers you get EVERY day. The pandemic brought a heap of luck didn't it? LOL. I hope you guys will still do your best to interact with us subscribers when you guys get million plus subscribers. That time is very near given the rate of views you're getting! I wish the best for you. I'm doing all I can to let people know about Cognito!
This video is quite confusing. It first says that the bonds between the atoms do not break, instead, the intermolecular forces break. This was said in the part about simple covalent structures. However, for the giant covalent structures, he states that the covalent bonds will have to be broken, instead of the intermolecular forces.
Hi there - yeah that is the main confusing point in this topic. For simple molecular substances it's the intermolecular forces (weak forces between the molecules) that need to break to melt the substance. Whereas for giant covalent structures (like diamond), it's the strong covalent bonds that have to be broken.

mitochondria is the powerhouse of the cell
cheers for saying this before a chmistry exam
after my biology test has already been done
much appreciated
😂
No it’s where aerobic respiration takes place
@@jill2252 yeah its the same thing. its called the powerhouse of the cell because thats where the energy produced for the cell is made
@@alextong2939 you won’t get a mark for saying that I don’t think
as a visual learner, your videos are more effective than my teachers' explanation
This channel needs more recognition
Cheers Oliver - really happy you think it’s helpful 🥳 good luck with all your work!
re cognitio n
who's here from a science lesson
it is now
@@shadowknights1385 yup
Omg i love this channel. I love how it’s so clear, yet very detailed and the videos are so short too. Imma turn post notifications on 😂😂
Aha thats great to hear - really happy you're continuing to find them useful!
Omg thx my dude u saving me from tomorrow's Chem test
Ahh good luck for tomorrow Mo! 🙌
@@Cognitoedu mines tomorrow too😮💨
@@WSDTY1 mines tomorrow aswell 😂😂
mine is tmr too :/
@@XRichKingX what did you get bro?
got my exam in half an hour wish me luck
Me too
I just wanted to take a minute and say that your page has really helped me a lot and honestly I am so glad you do these videos
Yaah for real it as been of good help to me😜😜
Just hats off.........

Thanks Cognito💙
Thx mate, surprised you don’t have more subs for the quality of these videos
Beautiful video bro, u just explained my doubts for the test I have tomorrow thx bro
Nice one 🙌 glad it could help you out!! Good luck for tomorrow ✌️
Ayyy same
My chemistry paper 1 is tomorrow, wish me luck 😅
Mine too 😂
U posted this 3 years ago, and I've got tell you that you are saving my gsce's right now.
nerd
Legit the only resource that explains science simply but still explains it well.
hahahahahhahahahahahahahahahahahah true
Great video and definitely learned something
Thanks Odo! Really appreciate the comment :)
I was gonna make a joke about Sodium, Hydrogen, Bromine and Oxygen but NaHBrO.
u just got me through my revision with that joke
Thanks so much Cognito! Youa and free science lessons are the only thing keeping my science grades up!😉
shut up br
This is one of the most informative chemistry videos I've ever seen! and all this in under 5 minutes?! this is just insane!
i literally owe everything to you . THANK YOU .
Mate you are saving my science gcse😂
you are literally a life saver.
I've never expected that a video, which takes barely 5 minutes to watch, could resolve my confusion better than a lengthy hour of studying in a seminar.
This is great!!! I have test coming up! I benefit a lot from this channel
these videos just turn summarise whole syllabus, so easy and fun👍
this is saving me bro i have a chemistry exam in 2 hours and these are my finals so tysmmmm for this its really helpful
i think this guy needs more support
Thank you so much for this video. It really cleared my confusion
The artwork makes it easier to understand
That’s good to hear 🙌
Thank you SO SO much this was so informative, clear and helped me a TON
hhaahahahahahahahahahahahahahahahahahahahhahahahahahahahahahahahahahahahaha
is it just me or The start sound of the video is SATISFING 0:00
This is so satisfying for some reason
Cognito you are a really great teacher
Thxx pale I got my chem exam tmr
Thxx for your lovely sharing
Good stuff hope it went well?
Cognito yeah good
Very helpful sir im grade 10 gcse student to refer RUclips is better than teachers honestly
clear and concise explanations, thank you
2:57 Joe Valent bonds
Jokes aside love the videos sir thank you
boiling point increases as you go down the group as the molecules get larger
Thanks a bunch Sir for making these humongously helpful videos on each and every topic!
I just wanted to know whether we should learn to draw these 3D diagrams in our chemistry IGCSE?
You don't need to, at least according to my teachers
Me when I see the quality of these videos 😳😳😳😳😳
thanks you so much for this video i did not know what i was going to write on my exam 😃😃
Glad we could help out! 👍
Without your videos, learning is impossible
dickriding go crazy💀💀💀💀
Simple covalent molecules MOSTLY do not conduct electricity. Aqueous solutions of acids and ammonia, however, do conduct electricity.
Question: Are covalent bond intramolecular forces?
I am really thankful for your videos
Why are there more intermolecular forces between bigger molecules???????????
There are more molecules on giant covalent structures so realistically more intermolecular forces to overcome
How come the melting & boiling points of single molecular substances are dependent on the intermolecular forces not bonds, but the melting & boiling points of giant covalent structures are dependent on the covalent bonds as opposed to intermolecular forces?
TY so much this rlly helps
yooo my chemistry teacher showed us this video
doesnt graphite have imf between the layers? and if so does that not affect the bp and mp?
Your videos help a lot
Excellent 👏👏👏
really helpful
Really amazing video 💖
dont know if youl see this, but what do you thibk will happen with GCSE exams this ya=ear.
(love the vids btw, best science youtuber out there)
👍 Thanks a lot!
love this acc sm
❤love it. Thanks a lot .
Hi man love this channel great man
Thanks man 👌

long mwssage
Thanks
Please also try to add computer science IGCSE course
nice video
Watching this day bf the test😅
very well explained
thx for vid
U need to be my teacher🤗🤗🤗
thanks 😀😍😃☺
How to know if a substance is a simple or giant covalent molecule based on its structural formula?
Hi, you can sort of figure it out, but it's quite complicated. It's best to just memorise the few examples of giant covalent structures.
Chemistry test in 2 and a half hrs:D
Big ups Maro and Lugi
Cognito, is ur channel for edexcel

Are there any more videos coming up??
Yes there are! Stay tuned!!

What is exactly meant by free electrons? I never understood that part.
The electrons are not on the outer shell of the atom so are free to move about
thx
goooooooooooooooooood
