Homework Help! Physics!!!

Hi!
I really need some help on my homework
These are the questions
1. Explain how a balloon is 'blown up' using ideas about particles.
2.Evaluate this statement
"If it wasn't for air pressure I wouldn't b able to drink through a straw".
3. Contrast the similarities and differences between drinking through a straw and how the Magdeburg Hemispheres work!
Thanks a million
Bye!!!

Welcome to TSR
Please take a moment to read the guidelines for posting questions.

In short they ask that you
- show that you have made an effort to do this yourself
- say what it is you don't understand or need help with
- tell us what you do understand so we can explain things efficiently

It asks that you don't post a series of question where it seem you just want someone to do your homework for you.

I don't really get the last part and the second to last part that's all
And I've spent like an hour doing the other "13" questions!
Thanks!

1. Talk about the pressure of the air inside of the balloon.
2. When you suck, you reduce the pressure in the straw (expand on this)
3. Talk about the lack of pressure inside the sphere.

Hope that's enough to be getting on with.
