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
Other Things About Liquids
• 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
The ‘Joker’ PowerPoint Virus Has
Started!
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.
