Okay, today's chapter is chapter 7 !
Everyone listen, okay no read carefully.
Aim is to absorb something into thee very important brain ;)






THE STATES OF MATTER.

Oh my.. can you guys even see the MATTER word? Ok. It's my fav colour, yellow 8)

As we all know, water exists in three different forms.

Solid water- frozen water and less dense than water. Example: Ice
Liquid water- is wet and fluid. For example: A glass of water!
Water as a gas—vapor is always present in the air around us, not able to be seen.

CLEAR?
Yes - thank you, you can scroll down. So smart!
No - Repeat reading again! Not stupid but just abit slow! ;)


Above are just definations of states of matters.
Now, we're going on to their properties!!!


(Heart shaped ice cubes!)

Solids have fixed shape and volume. (you can't possible put 1000 icecubes in a cup!)
Hard and rigid; large force needed to change its shape. (you can't change a square icecube to become a circle, can you?)
High density and incompressible. (COMPRESS ICE?!!?!?!?!?!?!? :/




Liquids have a fixed volue but no fixed shape.
It has a hgih density and it is incompressible 8)

Lastly, gases have no fixed shape neither fixed volume.
it has a low density and it is compressible!

EASY? YES? NO? Btw Im eating Ritter Sport now hehehe (y)

Now we've reached the kinetic model of matter!

Molecules in Gaseous state is packed very far apart while in the Solid state is packed very close together.
Remember: Solid first liquid second third gas ;)
And also, the closer the particles are packed together, the higher density they have

Now, for chapter 7, we're only left with BROWNIAN MOTION.
ok.. doesn't sound very appealing but indeed it's pretty interesting.

Okay whatever I can't seem to change my font back so I'm not going to change it back.


SO.. WHAT IS THE BROWNIAN MOTION?
To explain it in the very very super duper complicated way, it is:

Brownian motion (named in honor of the botanist Robert Brown) is the random movement of particles suspended in a liquid or gas or the mathematical model used to describe such random movements, often called a particle theory.

In a simple and very comprehendable way, it is:

• A MOTION OF SMOKE PARTICLES.


• HIGHER TEMPERATURE, SMOKE PARTICLES MOVE MORE VIGOROUSLY.

Okay please tell me you could actually understand that.

UH HUH! Einstein's Explanation of Brownian Motion!

Yes very important do take a look because it affects your understanding about this motion.
;)

Till then, thank you goodbye and God bless you Miss Wan!
