HELLO CLASSMATES!!!

WHO?

NOW LETS GET STARTED!

GasesBy: Samid Koch

Try Not To laugh

Forces

• Gases have no forces of attraction between the particles. The particles are far apart and free to move quickly in all directions.

CAN YOU SEE IT:As you can see the particles a moving In different directions. Most of them at least.

Shape

• Gases don’t keep a definite shape or volume and will always expand to fill any container. The particles move fast so they collide with each other and the container.

CAN YOU SEE IT:As you can see them moving fast

Compression

• GASES CAN BE COMPRESSED EASILY – THERE’S A LOT OF FREE SPACE BETWEEN THE PARTICLES

CAN YOU SEE IT:Where the arrow is pointing is the empty spaces can you see!

Density• Gases all have a very low densities ,

because there are not many particles in large volume

CAN YOU SEE IT:Here you can see a table on gas density.

THANK YOU!

LIQUIDS

Particles are the things that make up materials. If when a object is in it’s different states. The particles never change. However their density is different. Now I will tell you about the particles of water.

Particles

Particles of liquids are quite dense but they can still move around. That’s why when you pour a liquid into a container it makes the shape of the container. Here’s an example:

the DENSITY

• Liquids can flow very easily. You can see that when you see a river.

• Liquids are very hard to squish. This means when you try to squeeze it in your hands it won’t become get squashed.

• Also liquids have medium density. This means that most things will float on the top of liquid.

The Density• Solids have an extremely density to the point

that loads of particles can fit in to a small volume.

Forces• Solid have strong forces of attraction between

particles, and they have fixed positions. Sometimes they move around (‘jiggle’) a bit.

Shape• Solids have a completely definite shape and

volume, unlike gases or liquids.

Compression• The ease of compressing a solids are difficult,

as the particles are packed together.
