Вставка
- Опубліковано 27 лип 2024
- In this video we'll look at:
- How filtration can be used to separate insoluble solids from a liquid
- How evaporation can be used to separate a soluble solid from a solution
- How crystallisation can be used to separate a soluble from a solution

Hi cognitio I just tried out your website its awesome i can review my IGCSE materials now. Thanks! I will subscribe and support the channel.
And cant wait to see math courses! Thanks alot.
Can you do a video about Logic Gates, please? 😎
You guys deserv heaven to be honest !
No
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
thats so true, u got a like from cognito btw, i but i think u noticed already

I HAVE AN EXAM AND BY WATCHING YOUR VIDEOS I LITERALLY KNOW EVERYTHING
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

This man is the reason why I went from a straight C student to a straight A student in science, Tysm Cognito!
Great stuff my lad, keep it going
i have a test in two hours i needed this thanks
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 😊
Your videos are literally amazing, theyve helped me so much for my exams
Who else came here to review for a test?? And also this video helped my so much thx man :)
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!!!!!!!!!!!!!!!
Watching this before my Lab exam today. Thank you!! ❤
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
Cognito is the one thing getting me through exams, its so helpfull and its interactive aswell!
I’m in year 7 and I seriously need to watch this for my test
thank you sir you taught me more in a couple of minutes than what i learned in a 2 hour science class
I am here as science teacher said i should watch this but i am going to subscribe as this helps me a lot
A great video , got my chemistry assessment and seeing this made me understand it through ease .
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!!!!!
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!!!!
Finally an actuall good explanation that i can follow
anyone else got told by there science teacher to watch this
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!!
Thank you so much, this is gonna help me so much with my chem practical

Thank you, this will probably save my grades. 🙏🙏
Bro, still so useful after all this time❤❤
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
thank you so much it helped me for my science test and i got a great grade thank you!
Quareeb my student enjoyed the video... Thanks for the upload
THANK YOU! Was confused b/w evaporation and crystallization.
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!!
so much better than my teacher, thank u so much
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 :)
u deserve lots of subs
so.. not a single person can hear the music in the background?
or am I just imagining it?
hey thanks man this was pretty helpful
i think u are the best teacher i wish you were tutoring mee
thx a lot
how long do we have to keep the crystals in the oven?
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
@@Cognitoedu Making noise is my middle name ;) Thank you for this wonderful, informative video!
Sir your videos are very helpful. Thank you so much.
I am watching this the morning before my chemistry end of unit test thanks 😅
Hi
ur such a legend for this
This video help me alot
man ur video is very ezy to understand tnx :)
amazing video it really helped me
Really happy to hear it - thanks!
it really helped me, thankyou so much from the bottom of my heart

thanks A lot forgot this Im in year 8 lol
Your videos are great
Thx for this info really will help me in my chem assessment 😅
THIS HELPED ME SO MUCH
Filtration 1:05 Evaporation 2:03 Crystallization 3:10
Thanks denise 🤜🤛☺☺
@@Darknight-nv6ce no problem!
@@DeniseP where from u
@@Darknight-nv6ce aint no way
This is so good thanks
what do you think is the easiest way of separating mixtures
Tmrowss my exam....reallyyy helped!!
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 🖤
thank u so much..
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 :))))
You are the best teacher.and l will tall you thinks!
I’m so confused and I’ve exams next week 😭
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
ure my lifesaver bbg 💞💞
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
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 sm! reallyy helped
Did anyone else’s science teacher say to watch this video?
YES PAHA
Yes
yes my slime
indeed
Correct
It helps a lot 😊
Subscribed
Thanks for this video❤️😙
thanks you just made my lesson 10x easier it means i have more freetime for me to play! + 1 subscriber and +1 like
Me and leila olive mcgarry found this super duper helpful aww tysm pookie
Hey,
First of, I can’t thank you enough….Thank you,
And second, is there no #5?
How long does it take on average for crystals to form in crystallisation? Does it depend on the solution?
Probably
I will subscribe this guy one day 99.999%
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?
Thx alot dude
Who else is hear because of their science teacher ?
Meeeeeeeeeee!!!!!!!!!!!!!1!!😅
Do you mean that the colder the solution,more solid solute would appear?
