GCSE Chemistry Revision "Fractional Distillation"

[@genox633]

i hope you acknowledge that you singlehandedly assisted hundreds of thousands of people, we appreciate your consistency and hardwork.

[@Freesciencelessons]

Thanks for the comment. Science can seem hard for lots of students so I'm happy to be able to help.

[@ribbonandbows]

@@FreesciencelessonsI LOVE YOU SO MUCH SIR

[@cherryred5291]

thank you so much for making quick, 4-5 minute videos, no bs, just straight facts. I also love how the videos are separated instead of being clumped together and the dedication to making separate playlists for each level. I always know exactly what im watching, and I can quickly recall. Thanks!

thanks man im glad you're not fed up of doing this for the past like 6 years

[@Freesciencelessons]

It's actually been ten years. And I'm still not fed up doing this.

bro honestly youve helped me so much im praying you make alot of money from this cause u deserve it!

[@SpiccyS]

Night before my chemistry mock, you’ve probably saved me. You’re amazing.

[@Kvouka]

thank you so much for your work, I appreciate it so much, you’ve taught me more than school. Revising rn for a chem mock which I need the grade for chem a level

[@Freesciencelessons]

Thanks for the comment, I appreciate it. I hope that your chemistry mock goes well and you get the grade that you want.

[@NobAm69]

Ur learning this at A lv?

[@farzana5956]

Hello Sean, I want to thank you for all the videos you made. I watched every video for my GCSE exams through out year 11 as it explained everything clearly and in a simple way. I got a 9-9 in combined science :D Although I don't study a science at a level, I wanted to come back to thank you.

[@albudo64]

These videos are really helping me to revise for my mock, tysm appreciate it

i wish i used this back in year10 when my class didnt have a science teacher. youre saving my chem grade now tho

[@ServantOfAllah90]

just what i needed hydrocarbons in chemistry is kind of a long topic for me thanks for the help

[@Freesciencelessons]

No problem. The whole crude oil topic does contain a lot of content. I'm glad that you're finding the videos useful.

[@eesasarwar4342]

thanks for what you do, really helpful

[@Freesciencelessons]

No problem. I'm glad that you're finding the videos useful.

[@ST-ne3ws]

Hello! Just wanted to say your videos are seriously so helpful and good, extremely grateful. Also just had a question, are the content in these videos same as before? Or has the content / spec changed in any way? Ty!

[@NobAm69]

I can tell u it's all bout Science (prob)

[@Xi_Jinping_China]

Thank you this has helped me so much 😊

Thanks alot, found it very useful

[@Cody_studs]

I love your videos man, they really help. I have my GCSE next year, do we get the equations for it or not if you know?

[@twix3665]

Was all the editing done by yourself?

[@Freesciencelessons]

Everything was done by me.

[@grandesaba2189]

Hello, thank you for the videos :) May I ask why 3:05 ? Because liquid no 1 is not in the mixture anymore?

[@ayottvnow3691]

is this method of fractional distillation different to the one we use for crude oil, and if it is do we need to know both?

[@Freesciencelessons]

Yes the method is different although the principle of separating based on boiling point remains the same. You do need to know both.

Hello, will you be doing a level physics ?

[@Freesciencelessons]

Hi. No I have no plans to do A level Physics as I've never taught it.

your welcome @@Freesciencelessons

[@AdzHDYT]

do we have to memorise how the practical works

[@flameedits6488]

is this a reupload?

[@Freesciencelessons]

No I've redone the video. The sound quality and graphics are much clearer and I've included the text in the video, in line with my other videos. I'm gradually redoing all my GCSE videos.

[@BlueEner]

Cool

[@Freesciencelessons]

Thanks for the comment.

[@mineplayer1094]

I thought the chemical w the lower boiling point is heated until the boiling point and then it evaporates and condenses and the one with the higher boiling point is never vapourised. I’m confused!

[@VancouverVelocityFan]

👍

[@king_sayem4428]

I’m making notes but none of the info is getting inside me

[@Neodx2]

Just a question, When the mixture of vapours are passing through the condenser, how are we able to collect a pure sample of the lower boiling point liquid because wouldnt it be slightly contaminated? Do we have to switch beakers?

[@Freesciencelessons]

There will always be some contamination but if the temperature reading on the thermometer is constant, it will be a relatively pure sample. We can always redistill that sample to increase the purity.

[@TS4PFF]

thank you

No problem and thanks for the comment. I appreciate it.

does this come to year 10 exam ?

[@Freesciencelessons]

This is a year 10 topic.

[@car99g]

oh thanks@@Freesciencelessons

[@ILUVSTUDYINg]

Can you resit gcse science?

[@urdumb007]

You can but u have to pay, idk how much though. But if u fail it, you wont HAVE to resit them its only mandatory for Maths and English

[@alinawagner8]

fractional distillation so annoying

[@grandesaba2189]

Hello, thank you for the videos :) May I ask why 3:05 ? Because liquid no 1 is not in the mixture anymore?

[@Freesciencelessons]

80oC is the boiling point of the lower-boiling point liquid in this example. So when the temperature reaches 80oC, the lower-boiling point liquid boils and that is the main vapour passing over the thermometer.
