Mlungisi Nkosi is literally saving my future at this point 😭👍🏼because I need to get good marks for my varsity acceptance, especially for physics. Thank you for being able to explain work in a manner we can all understand!. I've been watching you since Grade 10 and my understanding of physics has improved. Thank you ❤️

[@MbalienhleNgwenya]

Hi did you pass your matric❤

[@Juss-elos]

Hi ❤️ I'm currently doing my matric year and I got a 78% for my Physics March test. Mlungisi Nkosi really did a number for me during my time of studying for the paper

[@UrbanTwilightt]

this is the best video ever on intermolecular forces, from this video i got an A on my test and even impressed my teacher with my answers. couldnt have done it without this vid thank you!

[@MlungisiNkosi]

You’re welcome and thank you 😊

[@oritondanemalale4674]

You must realize that this videos or lessons you put on this platform are timeless. This is still going to be relevant for quite some time and, even the future generation will make use of them . Chief , keep doing what you do best 🙏

[@NosiphoMdletshe-ch2dq]

I'm rewriting my matric this year and I've been watching all your video from physics to chemistry and I know I will pass physical science this year you've helped me so much with your videos thank you so much sir

[@saladbee]

Through you,l can now explain to my classmates without hesitation, you are the best, from kenya

[@enemithytr215]

You are called.🙏🏾 You truly are the best Physics teacher ever. ;)

[@mphosinethemba7554]

Do you think it is possible to get a distinction for physics at the end of the year if you were getting 60s during the year?

[@MlungisiNkosi]

Absolutely... You keep chowing these videos like it's the last thing on earth, and get enough practice with past papers. Lalela... Nothing is impossible. Just check the comments of other people... You'll see.

Sir i was told that phase is never considered because it involves the intramolecular bonds

Hello there sir.. I am really struggling with kc value hle.. Like I don't even have light on what's going on😢

[@Thebiblecorner.]

I think he has a video I learnt there

[@MlungisiNkosi]

There are lots of videos to choose from under playlists.

[@boingotlomokgethi5605]

Quick question,do they penalize us if we write CH3 instead of breaking it down???also when writing a structural formula,is there a specific side we should start on,like for instance maybe adding our alkynes and stuff??? because according to me its the same answer,but I need to know if there is a preferred starting point or either way is fine as long as the numbering is correct... I need to know this before I write tomorrow so please do respond. Thank you

[@Envyius]

hi sir, i was wondering why it is that alkynes or alkenes will have a lower bp compared to alkanes ? is it because of the number of imf forces between them or something else

[@cleopatralove6872]

Hi sir🌈 When ever you can, please can you do a past paper on the reactions part of organic chemistry & please can you explain and maybe do a past paper question on polymerization

[@MlungisiNkosi]

I will record it first thing tomorrow morning. I've been meaning to do that.

[@coleabrahams9331]

My physics teacher said that they took out polymerization out of the syllabus though, so I pretty sure we won't be examined on it

[@MlungisiNkosi]

@@coleabrahams9331 yes it is true...

[@phalanekagiso5499]

Can you please do this with chemical equilibrium .. how to explain and also please upload all the types of rate of reaction vs time graphs 💔I'm really struggling with chemical equilibrium

[@MlungisiNkosi]

Check under Playlists

[@DitshwaneloMaponopono]

Sorry sir , can you please consider that part whereby we are talking about Degree of branching (shape) , So I wanted to ask if I'm correct if I write it this way 👇 Compound A *Large surface area *Strong intermolecular forces *More energy required to overcome the intermolecular forces Compound B *Small surface area *Weak intermolecular forces *Less energy required to overcome the intermolecular forces

[@KwaneleCapha-kx8jx]

Can u plz further explain the one about the shape of the molecular

[@reitumetsechaisi5268]

Hello sir, would it be possible for you to make a video on polymerization ? Thank you so much for all the videos.

Apparently, it's been trimmed out.

[@samusicentertainment3163]

Can I also say “more energy is required to overcome the bonds between molecules “

[@MlungisiNkosi]

No… That is a very common misconception. It’s not bonds that are broken but a separation of molecules

[@samusicentertainment3163]

@@MlungisiNkosi thanks sir , Noted

[@ngeni_za]

Good day sir, provided we have a secondary/tertiary alcohol and a carboxylic acid, will the carboxylic have a high boiling point or they'll differ due to an increase in Oxygen(O) in the alcohol compounds

[@MlungisiNkosi]

Yes carboxylic acid should still have higher BP due to the two sites of Hydrogen bonding.

[@tsireletsolentsa7883]

Carboxylic acid has both hydrogen bonds and dipole - dipole forces

[@mendrewmabuza]

What about melting point, Mr Nkosi?

[@MlungisiNkosi]

The concept of melting point is similar to that of boiling point. Although it applies to different phases

[@MlungisiNkosi]

Please email us

[@ponimyeza]

Why not break the bonds cause in memorandum they say break I am curious

[@MlungisiNkosi]

These are INTERmolecular forces, not INTRAmolecular. The former are forces of attraction between molecules, the latter are bonds that form between atoms

I take VERY GOOD NOTES , my strategy plan is looking good , I watch a lot of your videos and I have every resources I need to pass but I keep getting average marks 🥲.I showed my teachers the way I practice and they also reassured me that I do it in a good way . Please tell me what I'm missing because the only reason I think that causes all of that is test anxiety maybe . Please help while it's still early .

Please add practicing using past exam papers to that strategy
