Hello, i really find your videos helpful. Would it be possible if you could make questions suitable for WJEC exam board as its quite different to other exam boards i think thanks
@@krishnachopda1062 be so fr rn lmao, it is science no matter what. just bc its basic doesn't mean its not science what type of logic is that? many of the main concepts are formed only bc of the basics.
My friend sent me this video, and this video has helped me so much! I have a exam tomorrow, and this 4 min video made this whole topic understandable for me. Thank you so much!❤
It took my teacher 15 hours to explain this, meanwhile you explained it in 4 minutes. Several students fainted due to heatstroke and a lack of food or water in the classroom however the teacher insisted on not letting us out until she had taught us for 15 hours. One student had to be escorted to the hospital, thank you for this video.
The video explains the three states of matter - solid, liquid, and gas - and how substances can change between these states through changes in particle behavior and energy. Key moments: 00:04 This video explains the three states of matter - solid, liquid, and gas, and how substances transition between them using particle theory. It details the behavior of particles in each state and the changes that occur with heating or cooling. -Explanation of solid state with strong forces of attraction, fixed position of particles, and vibration leading to melting point and transition to liquid state. -Description of liquid state with weak forces of attraction, free movement of particles, and ability to change shape while maintaining volume. -Discussion on gas state with very weak forces of attraction, free movement of particles, lack of definite shape or volume, and behavior when heated or cooled.
Correct me if I am wrong but bonds are not broken during heating or cooling of substances. Attraction between particles are overcome. Great video though thanks!
yes but to make the particles to overcome is by heating " bonds between these atoms are broken down due to heat causing the attractions between the particles to overcome "
I’d also recommend to people , the account “chemistry by sir osama sahab’ he first talks in his native language but just skip a bit till he speaks English, his videos are outstanding !
since all molecules and atoms are spherical in shape whirling around each other in a spherical pathway/orbits... wouldn't that mean all forces are spherical in nature... regardless of the state there in and how they are arranged ... if we look to the point where any matter is then we are more apt to understand our surroundings and ourselves .. after all.. we're all made up from them

Thanks Sovereign! we really appreciate it 🤩
thanks a lot. I have a bio, chemistry, maths and physics exam in the following week and I can't thank you enough for all the videos you did. Thanks
i have an exam on this in 20minutes!!! thanks so much
our pfps are having a conversation 😭🤣
Thank you so much this was really helpful I have exams coming up and you just explained everything in 4 mins great job honestly 👏
This video made me understand a lot of things in just 4 minutes thank you
That's the aim! Thanks Mejiyo 😊
U can turn water into a gas without separating it into its main componites or turning into something else
Our science teacher sent the link to watch this
Thank u for ur explanation! :-)
so like this explained more than my actual school book
Yes

Btw the 'force of attraction' can also be called as the intermolecular force.
To be honest! This made me understand this so much quicker! Thanks Cognito!
Ah awesome, thanks Torxado!
youre amazing the way you explain science is insane it make me actually understand whats going on
this man teaches a 50 page chapter in 4 mins tysm bro
This might be the most ive ever understood from anything. Very helpful
Thanks Dude appreciate it a lot got a physics exam tomorrow and ur video just might get me above 60%
Thanks man
Great work. Going to show this to my physics class.
omg sir...

Wow I love the explaination, quiet easy to understand
Thanks for this in just 4 minutes!!!!!
dose your channel cover edexell or aqa ?
Pov : teacher: 2 weeks to explain all this
cognito: does it all in 4 minutes:)
well done cognito!
this is a very clear explanation. thanks
thanks alot this really helped with school , really needed to understand this for physics 💯
Glad it helped! 👍
Very straightforward, thank you.
How do liquids have a lower density than solids - water expands when it freezes into ice
when energy is supplied to the particles in a solid to weaken them, does the energy necessarily have to be heat?
Thank you very much Sir. It has really helped me.😊❤
Me: Teachers are so boring, takes 3 weeks to complete a lesson.
You: 4 minutes and presto, it's done!
I'm watching this full volume in class
I looking for Theory particles was explained theory quantum. Can you help me? Thanks.
Thx for this video it’s so useful
Was also told to watch this cuz of a science lesson but it pretty nice i like this
thankyou for this
it helped alot
Glad it was useful 👍
Thank u soo much😄

When is the best time to start revising for the science exam? Correct, 30 minutes before it)
Revision for mocks ty
YOUR VIDEOS ARE SOOOO GOOD!!!!!!
Nice dude explained teachers every 1 hour lecture in 4 min
guys doesnt anyone notice he sounds EXACTLY like misterwhostheboss
Not really I think 10 octaves lower (higher voice)
Nah I don't think so.
Sorta?
Bro, Thank you sooooooooooooooooooooooooooooooooooooooo much, you are truly a life saver
Hey cognito! Sorry my son was watching this on my youtube account. Is it ok if I use this for my grade 7 students?
Yeah of course it's the best in the world so actually this account is a very good friend if mine
LMAOOOOOOOOOOOOOOOOOO
great work ..May i use it to help my students ?
Please do :)
thank you so much
kinetic particle theory in physics is the same as kinetic particle model in chemistry????
amazing explanation! thanks

Ice is less dense than liquid water.
Nobody asked
Team Loyal 😂
Yes solid water is less dense than liquid water🤓🤓⚛⚛⚛
*physics is strange*

Thank you for making this vid
You are a live saver,I have a quiz tomorrow
Hands Down, Best explanation about Particle Theory.
these videos are really awesome
What happens when solid matter is crushed, smashed, grinded or broken in pieces? How can we explain it using particulate nature of matter?
"This was sick!" - My students
Is it intermolecular forces that keep the particles together in solids and liquids?
Thank you so much it helped me a lot.
Thank u science dude u rock all dat in 4 minutes man#geneous

what about solids directly changing into gas?
If all teachers did it like this the school year would have been wayyyy shorter
since all molecules and atoms are spherical in shape whirling around each other in a spherical pathway/orbits... wouldn't that mean all forces are spherical in nature... regardless of the state there in and how they are arranged ... if we look to the point where any matter is then we are more apt to understand our surroundings and ourselves .. after all.. we're all made up from them
no not all atoms are spherical theyre actually different shapes
It was really helpful
What about plasma
thank you for the video
I was only taught like 4 States of matter
Theres only 3
This is gonna save me from my homework 🙂
this was so helpful!!
isnt plasma a matter too? heard something about that once , so can someone clarify pls
I think it is just search it up if ur not sure but I’m pretty sure I heard it too once
Great teaching
Really great VDO .....👌👏
Really good
This is literally the same thing as "GCSE Chemistry - States of Matter & Changing State #21" but the end is a little different.
loved the vid!!!!!!!!!!!
