The Kinetic Theory | GCSE Physics | Doodle Science

Here's a new Doodle Science video! Please Subscribe and Like if you enjoyed the video and want to see more! This is my new Channel just for Doodle Science videos.

Script:
1. The kinetic theory explains the properties of the different states of matter. 2. All the particles in a solid liquid and gas are the same, the only thing that changes, is the amount of energy they have (turbine drawing). 3. Solids have a low amount of energy, too low to overcome the strong bonds that hold the particles together in a regular pattern, but not too low to stop movement all together, as they still vibrate about a fixed position. Solids are also incompressible because there is no free space for the particles to move into. If we give a solid some more energy, it will eventually loosen the bonds between the particles and allow them to move over each other and take the shape of its container, which is what we call a liquid. Similarly, liquids cannot be compressed because there are no free spaces between the particles. Which is why, if you were to jump of a really high diving board, the particles in the water below would for a split second represent the properties of concrete because the particles haven't had time to move out the way for the unfortunate diver. Gases have a lot of energy and move about their container very quickly and unlike solids and liquids, they can be compressed because there is lots of space for the particles to move into. Which is how a paintball gun works, by compressing the air very closely inside a tank and releasing it 4. in a short burst to propel the projectile onto someone's backside. OUCH!

Oh dear... I'm in the middle of my exams rn and I regret every single hour I wasted procrastinating... It's so stressful because I have given myself no choice but to revise a couple of days before the actual exam for every exam... PLEASE LEARN FROM MY MISTAKES YEAR 10's! I have never not worked hard for my grades (like seriously hard) but I wish I had put more effort into finding the time to work hard... Oh well, can't change the past. Ugh Physics Unit 1 tomorrow and dreading it. Good luck anyone doing it tomorrow! xx

Who the hell would dislike this video?? This guy is a pure genius!! Since ASAPscience and minute physics does videos for more non-high school related problems and concept, it would be awesome for someone like you who does videos on basic high school science concepts like kinematics.

Shame on you dislikers (unless there is actually something significantly wrong with the video that defies science, if there is, what is it???)

You have started a journey that will change the world. Don't stop!

This youtube channel is saving my GCSE revision.

This is a good "Analogous" explanation. You really need the caveat that this isn't actually how it works, but how it's a good approximation for certain scales of energy/size. Maybe, you should also touch on where actual physics starts to break the analogy. "And I cannot make it any simpler, I'm not going to do this, I'm not going to simplify it, and I'm not going to fake it. I'm not going to tell you it's something like a ball bearing inside a spring, it isn't."

Keep doing this, and you will become something a lot of people would subscribe to.

Have to watch this for my science class 😂

There is a difference between flexibility and compressibility. If something is uncompressible it means its volume remains constant under pressure, not that you can't change its shape. Technically all solids are slightly compressible, but in general it it very difficult to change their volume and rubber is no exception.

Imitation is the sincerest form of flattery. Or so "they" say. I find it odd that people are being so negative about this with regards to it copying Henry's style from Minute Physics. I came here via Minute Physics channel as he "liked" it. I suspect that he subscribes to the ideal that people can/should learn more. It doesn't really matter how we get there.

Good on ya for this informative video and try not to listen to your detractors.

[KillerTunesKiKo]

Thanks man, got my gcse exam tomorrow.

[queensama]

This taught me more than a year in school

[PepePopo]

it comes from an energy source... for example, the sun.... or methane combustion when you heat water in your kitchen....
but I guess your question is about something like oxygen, which is a gas at room temperature, there are things that he didn't mention like interactions between molecules... those interactions are weak in oxygen, so room temperature is enough energy to have gaseous oxygen.

[danielsmith]

I don't mind about the style, many people do this sort of style, Asapscience, sciBRIGHT, Minute Earth and many others use whiteboards (so do teachers, it's an easy way to learn). But I agree with the type of animation, that's a complete copy.

[morgengabe]

I would say one thing, at around 00:36 you say that liquids take the shape of their containers, which they do, but I think you mean Fluid, because liquids aren't the only substances that do this, solids of the right size in the right container can do this.

Other than that, I liked this.

[CalvinizedSteel]

You, Sir, will be with Vsauce, MinutePhysics, The VlogBros, ect. very soon. Keep up the good work.

[DonkeyPunches]

You're not dumb, if only because that was the most mature response I've ever seen in youtube comments

[wrweeks]

It should be noted that Minute Physics liked this.

[krise]

You my friend deserves a lot of subscribers and i really hope that you will become famous someday! Keep up the great work!

[DJDanLogic]

Very simple concept. But you've definitely got what it takes. Well produced. Like'd. Good luck.

[livedandletdie]

Well so are solids as well though it's futile to do as the force needed is extreme.
And it also depends on the liquids intermolecular structure on how much they can be compressed. For instance it requires less energy to compress ice than water.
