Good afternoon sir, I have a question that I would like to ask, The question states that the boiling points of methanol, ethanol and water are 65°C, 78°C and 100°C respectively, and the questions is: Name the substance that was separated first from the mixture. Explain your answer. I answered it as Methanol, but I don't know how to explain it. Please help me and teach me how to write the explanation. Take your time and thank you.

@@user-yf8wl6ss5bI’m not 100 percent sure and I probably wouldn’t even listen to myself(im 14) but I would say it would be methanol because it has the lowest boiling point so it will turn into vapor first and go through the funnel and into the condenser before the rest of the substances can turn into vapor this probably won’t help you get the marks but I hope I helped

I got an 8 in all my science GCSEs and couldn't have done it without you. I am a home learner aged 18 who left school at age 12 for various different reasons, so I missed out on a lot and decided to relearn a lot at age 16-18 and self-taught using your videos and completed my separate sciences in just 8 months and achieved a grade 8 and I am so thankful for your videos.

Hi Murgan thanks so much for the kind comment - really happy to hear it helped you out! Good luck with all your work ✌️

I searched many videos belonging to this distillation purification but couldn't find and luckily I got this video it's very easy to understand. Thank you

My book makes this needlessly hard. You make it so easy.

I swear you explained 50 times better than my teacher. I really appreciate how you put visual presentations in your videos like diagrams and colorful animations and explain in just 5-8 minutes. As an IGCSE student, they help me grasp ideas and understand the concept more clearly than just a 45 minute explanation with little or no diagrams. Thanks a lot, sir. Please don't stop making videos that really help people get good grades in their exams. 💗

I have referred many videos before on this topic but this is the real winner . Eye opening concept@4.31 Thanx a lot 😊

I have a test tomorrow and BOY your a lifesaver thank you

Prolly the best channel ik, I learned a lot from this guy then my teachers ig

really helped it. i just failed a science test, but i will never give up. and thank you for the info abt fractional distillation and simple distillation! :)

Honestly ur videos are the best ive found and cover so many topics. Lifesaver for my GCSEs lmao

Hi, my science teacher sent my class this link to do work. This makes it very easy to understand. thank u.

this is the only only video from which i understood the toipic made it so simple.Thank youu

Oh my god! I never understood this concept and you made it so easy! Thank you so much!!

I don't think I could ever fully express how helpful this video was

Thank you so much for your videos, I am trying to revise for a test and I found the revision guide hard to understand, but this video made it much simpler. Thank you! :)

Helped in My Test didnt understand from the teacher and found the real teacher Cognito

They have helped me so much with understanding science thank you Cognito

whenever i have a science test i come straight here

this is a great explanation, why ? distillation isn't a simple task to explain but he did it in just a few minutes by breaking down the most essential parts which led us to understand the topic easily I am so thankful for this !
