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.

Page 8: HELLO CLASSMATES!!!

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

Page 9: HELLO CLASSMATES!!!

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!

Page 10: HELLO CLASSMATES!!!

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.

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

Page 16: HELLO CLASSMATES!!!

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

Other Things About Liquids

Page 18: HELLO CLASSMATES!!!

• 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.

Solids• By Fayadh

Page 25: HELLO CLASSMATES!!!

The Density• Solids have an extremely density to the point

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

Page 26: HELLO CLASSMATES!!!

Forces• Solid have strong forces of attraction between

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

Page 27: HELLO CLASSMATES!!!

Shape• Solids have a completely definite shape and

volume, unlike gases or liquids.

Page 28: HELLO CLASSMATES!!!

Compression• The ease of compressing a solids are difficult,

as the particles are packed together.
