Science chapter 8 test

hey, this is just a basic quizzing thing for our science test monday! omg, i was at at the venturi effect when i accidentally pressed backspace while it wasn't on a little space thing, and it pressed "back" and it wouldn't let me go back!! so i had to retype EVERYTHING!! that's why it took so long, sry. ttyl. good luck with studying and stuff!
