Can we just appreciate how this man still interacts with comments after 4 years? Your videos are incredible, you have produced some remarkable work over the years that has helped millions of other students like me in their GCSEs. I hope you the best of luck in your journey man, peace
i aced all my science exams because of you!! i never understood anything that was going on in lessons and this channel helped from knowing nothing at all to understanding the whole chapter! Thank you so much!
I’m a mum looking for ways to support my daughter and your videos are BRILLIANT. I can understand to support her and she can use the materials to aid her revision. Thank You
I have my first Chemestry exam on Thursday and I can't thank you enough for the extra help with these videos, I came across them while trying to find something that would help with my exams as I was struggling to find out how to study, and these videos help so much Had a Biology exam today and the biology videos helped with that a lot
Thank you Cognito :) This really helped me a whole lot, I can't focus in class and don't understand but thanks to this, I really understand Yaayy!! Hope this video gets a lot more views 😉 This is the only video that was complete that I could find
Cognito, your videos are no joke AMAZING. You explain stuff so nicely and well done in just 5 minutes, and that’s why I pass my exams, all thanks to you guys. This is why i subscribed to you, and please carry on the tremendous work your doing!!! You’re only helping more and more people with each subscriber and view you get, which I think that’s amazing. I’ll start recommending you to people who are struggling with this, and hopefully they will start watching you to. GL!!!!!
Hi, this video is absolutely amazing i am going throught the whole chemisty topic on your channel for my scinece exam tommorow, even though i am jn year 9, in 2 gears for my GCSES i will come.back and use this, thank you so much
i actually do not know how to thank you enough for these videos edit* btw im 15 in year 10 i will update you after i finish my gcses i only rely on your videos, cgp sometimes and past papers for revision so hopefully its worth it because these are definetly the best revision guides to exist
Thank you so much cognito, you help me in chemistry and biology as well math, u are the best teacher and sometimes I just wish that you would be my teacher.I am sure everyone would like that to happen. ❤❤
My finals are going on and it is my chemistry exam after 2 days. I love your videos as they help my to understand things more clearly they really help! keep it up!!!! LOVE YOUR VIDEOS!!!!!!!!!!!!!!!
Question: Then why don't we form crystals in fraction or simple distillation when we evaporate all of the elements to leave one element left in a flask?
so basically, evaporation is easier, but we do not get back the solvent whilst crystallization is longer, but we get back both the solvent and the solute. thank you!!
I'm year 9 and we've had online school for a while so I haven't really learnt anything since the start of the year and I have a really important test tomorrow so yay 😩🤞🏽
wow amazing this helped me soo much i have a chemistry test tmrw and you literally covered all the topics like an expert!!! My chemistry teacher can resign now!!!!
I did not understand that in school as my friends and I were making noise .The entire class was not lustening and taking notes but i took the notes . Even with notes i did not understan but now yess tomorrow is my exam . Thx💥💯
Hi deepa thanks for such a lovely comment. It’s really great to hear the video was useful to you (and it’s really helpful for us to get comments cos it boosts the videos up the search rankings!) so thanks so much for taking the time to let us know! Good luck with all your work. Also I spent my entire GCSE making noise / setting fire to magnesium too, so can totally relate haha
My exam is in next week and my che tr has already revision all the lessons but i still don't get it then i found this Channel to save me and understand the concept 🖤
These are summer vacations going on and I'm sure,thanks to you, that after summer vacations, I'll be a top student in studies. Ahahahahaahhaahahahahhàahahhahahahhaha

YES PAHA
Yes
yes my slime
indeed
Correct
bro you are under rated but best teacher of chem on youtube
im in school and you are one of the first people to make me understand how Crystallisation thank you keep up the good work
That's great Liza, glad we could help 😊

Who else came here to review for a test?? And also this video helped my so much thx man :)
I’m in year 7 and I seriously need to watch this for my test
Just going onto mocks and this helped sm tyyyy
i have a test in two hours i needed this thanks
I am here as science teacher said i should watch this but i am going to subscribe as this helps me a lot
got a test tomorrow this video helped me understand a lot more
fr me too bro i got my O level chemistry P1 and P2 tomorroww
BRO U ALWAYS SAVE MY LIFE ❤!!
Hi, this video is absolutely amazing i am going throught the whole chemisty topic on your channel for my scinece exam tommorow, even though i am jn year 9, in 2 gears for my GCSES i will come.back and use this, thank you so much
My exam is coming up next week and the first thing that came to my mind while reading chemistry was your channel
so underrated!!
thank you sir you taught me more in a couple of minutes than what i learned in a 2 hour science class
honestly you are the best
your going to help me smash my exams
Keep it up Cognito! my brother used this to study
i actually do not know how to thank you enough for these videos
edit* btw im 15 in year 10 i will update you after i finish my gcses i only rely on your videos, cgp sometimes and past papers for revision so hopefully its worth it because these are definetly the best revision guides to exist
please reply I don’t know what sieving and the mixtures of sieving
I don’t know what evaporation is in mixtures
filtration, distillation and flotation
Cognito is the one thing getting me through exams, its so helpfull and its interactive aswell!
Thank you this really helped with my Science homework ❤
You've been on of the best things that has happene to me
had 2 hours of this lesson and could not understand anything, this 4 minute video did thank u.
Quareeb my student enjoyed the video... Thanks for the upload
Thank you so much, this is gonna help me so much with my chem practical
I can't believe it you should have a million likes !!!!!
Thanks for the support, and for taking the time to leave a comment - give it a few years maybe we will!🙃
Good luck with all your work!!
so.. not a single person can hear the music in the background?
or am I just imagining it?
A great video , got my chemistry assessment and seeing this made me understand it through ease .
Thank you so much cognito, you help me in chemistry and biology as well math, u are the best teacher and sometimes I just wish that you would be my teacher.I am sure everyone would like that to happen. ❤❤
Your videos are literally amazing, theyve helped me so much for my exams
This is the top g in education right here 😂you helped a lot in my gcse and saved me ours of revision
anyone else got told by there science teacher to watch this
Watching this before my Lab exam today. Thank you!! ❤
Why don’t you leave everything to dry? Couldn’t there be crystals that are still mixed in the solution that you filtered out??
ull just end up evaporating all of it and leaving the bit of solute to form with defects
Thank you, it was very helpful and I understood about the topic very thoroughly .
That's great Krishitha, glad you liked it 😊
Finally an actuall good explanation that i can follow
Subscribed! Really helped me! I’m in Year 7, and have my science assessment soon thanks!
Hi N, thanks for comment and really happy to hear you’re finding them useful!! Hope all your work goes well :)
it really helped me, thankyou so much from the bottom of my heart
Who’s Chemistry teacher sent you this?
hey congnito!
thank you for this vedio i am sure i will score good in my exams now (tommorow is my chemistry exam) THANK YOU SO MUCH......!!!! :D
update pls how much u got
im hoping its good
i think u are the best teacher i wish you were tutoring mee
thx a lot
My finals are going on and it is my chemistry exam after 2 days. I love your videos as they help my to understand things more clearly they really help! keep it up!!!! LOVE YOUR VIDEOS!!!!!!!!!!!!!!!
how long do we have to keep the crystals in the oven?
I am watching this the morning before my chemistry end of unit test thanks 😅
Hi
Question: Then why don't we form crystals in fraction or simple distillation when we evaporate all of the elements to leave one element left in a flask?
thank you so much it helped me for my science test and i got a great grade thank you!
Thank you, this will probably save my grades. 🙏🙏
Hey,
First of, I can’t thank you enough….Thank you,
And second, is there no #5?
so basically, evaporation is easier, but we do not get back the solvent whilst crystallization is longer, but we get back both the solvent and the solute.
thank you!!
My test is in a day and ur video really help thank you so much
Best of luck!
@@Cognitoedu Thank you so much i passed :))))
so much better than my teacher, thank u so much

wow amazing this helped me soo much i have a chemistry test tmrw and you literally covered all the topics like an expert!!! My chemistry teacher can resign now!!!!
i have a quiz tomorrow and this really saved me. thanks!
This video help me alot
THANK YOU! Was confused b/w evaporation and crystallization.
Love the videos but can you do questions and answers at the end
Bro, still so useful after all this time❤❤
amazing video it really helped me
Really happy to hear it - thanks!
Loved this for my chemistry class / revision. Amazing job !
Mahnn, this is incredible.... Thank u so so much😊
I did not understand that in school as my friends and I were making noise .The entire class was not lustening and taking notes but i took the notes . Even with notes i did not understan but now yess tomorrow is my exam . Thx💥💯

@@Cognitoedu Making noise is my middle name ;) Thank you for this wonderful, informative video!
Do you mean that the colder the solution,more solid solute would appear?
Please where is video Number 5?
My exam is in next week and my che tr has already revision all the lessons but i still don't get it then i found this Channel to save me and understand the concept 🖤
How long does it take on average for crystals to form in crystallisation? Does it depend on the solution?
Probably
2:46 someone help what does he mean by that word?
Like when it decomposes, it breaks apart (more or less I’m not English native and learn this in English so it may be wrong)
some solids decompose when being heated. The bonds in the solid break
what do you think is the easiest way of separating mixtures
Sir your videos are very helpful. Thank you so much.
is it appropriate for Olevels chemistry 02
Who else is hear because of their science teacher ?
Meeeeeeeeeee!!!!!!!!!!!!!1!!😅
These are summer vacations going on and I'm sure,thanks to you, that after summer vacations, I'll be a top student in studies. Ahahahahaahhaahahahahhàahahhahahahhaha
You are the best teacher.and l will tall you thinks!

Quick question what does susceptible mean ?
It’s likely/ possible for it to happen. If I’m susceptible to infection, it is possible I will get infected.
