  4. Gases By: Samid Koch

  5. Try Not To laugh

  6. 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.

  7. 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

  8. 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!

  9. 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.

  10. Thank You!

  11. Liquids

  12. Particles 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.

  13. the DENSITY 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:

  14. OtherThings About Liquids

  15. FaCtS • 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.

  16. Thank You For Listening

  18. Solids • By Fayadh

  19. The ‘Joker’ PowerPoint Virus Has Started!

  20. The Density • Solids have an extremely density to the point that loads of particles can fit in to a small volume.

  21. Forces • Solid have strong forces of attraction between particles, and they have fixed positions. Sometimes they move around (‘jiggle’) a bit.

  22. Shape • Solids have a completely definite shape and volume, unlike gases or liquids.

  23. Compression • The ease of compressing a solids are difficult, as the particles are packed together.
