Air pressure?
I was doing a lab for my chemistry class but my hypothesis did not come out the way i had predicted. The experiment is with a graduated cylinder and a water dropper. The cylinder is covered on the top w/ a balloon and a rubber band. Can you please help me with these 2 questions?
When air pressure increases, the volume of the air?
When air pressure decreases, the volume of the air?
Thank You for your help
=)
Recall Boyle’s Law, Pressure*Volume = Constant (at a given temperature and fixed amount of gas).
When air pressure increases, the volume of the air decreases (for a fixed amount of gas at a constant temp)
When air pressure increases, the volume of the air increases (for a fixed amount of gas at a constant temp)
