  1. Hi, I am William.
  2. Uh, I'm doing a president.
  3. This president video on the four chemical changes.
  4. Please excuse costing.
  5. Biggles precipitate energy exchange, color change and gas production.
  6. Um, precipitate is when you pour to liquids together and
  7. it forms a solid.
  8. So like when you pour, I guess like some kind
  9. of black wit liquid and some kind of like blue
  10. liquid. And you pour them into the same like jar
  11. they would They could become a solid or have solid
  12. particles, which means, like, 80 bitty itty bitty, um, anybody
  13. solid flex, they go to the bottom of the container
  14. or vile?
  15. Uh huh.
  16. So, energy exchange is when Luminal and blood, That's what
  17. some scientists use in crime scenes.
  18. That's, uh, well, they help police officers basically, and they
  19. go to crime scenes, and they basically sport the whole
  20. scene and the weapon with Luminal.
  21. And if it turns a light blue, that means there
  22. was blood on that item or around the room.
  23. Sorry. I don't know if you can hear me better
  24. or not now, um, but ah, energy exchanges when it
  25. produces a light or the temperature increases or decreases, so
  26. moving on to color change, color changes where it's unexpected.
  27. So if you paint a white wall orange and it
  28. turns purple, it's probably not gonna happen, because I don't
  29. think that's possible.
  30. But we don't know it could, Um, honestly, it could
  31. happen. The world is weird, like, really, really weird.
  32. Um so Okay, it would be an unexpected color change
  33. if you painted the wall orange and its state well,
  34. whitewall orange and it stayed orange.
  35. That would not be a color change that would just
  36. be you painting your wall.
  37. And of course, it's going to be orange because you
  38. painted it orange.
  39. But if it turns like purple or something, when you
  40. painted a white wall orange like or like mixing a
  41. light blue liquid with a bright green liquid and it
  42. turned, let's say pink.
  43. I don't know, Um, like pink like the shirt.
  44. Yeah, sorry I had to fix my headphones.
  45. Um, that would be a color change.
  46. Now gas production is fizzing.
  47. Bubbles or odor.
  48. Fizzing is just like bubbles, but bubbles are more spaced
  49. out. Odor is another word for scent or smell.
  50. The across stick for that would theocratic for precipitate energy
  51. exchange color change and gas production is Please excuse coughs
  52. and giggles.
  53. It's awesome.
  54. Um, well, that's basically it.
  55. Um, thank you for watching this video.
  56. I appreciate it.
  57. Please don't mind the last slide and you are as
  58. free as a bird, including this pick.
