To determine the relationship between the pressure applied to a gas and the volume it occupies.

we will change the pressure in cylinder by adding a number of books on the top of the piston to reduce the volume in cylinder .the rersult was

volume numder of books

19.9459 L 0

4.5289 L 3

2.6578L 6

1.5241 L 12

0.9821 L 19

 

 

1.How does the mass of the trapped air inside the cylinder compare for each try?

1. What does the relationship between P and 1/V?
2. What the relationship between P and V?
3. When there are no books on the piston, what pressure is still being exerted on the trapped gas?
4. Use the KMT to explain why decreasing the volume of a gas increases its pressure.
5. High-altitude weather balloons appear to be under-inflated with helium when they are released. Use Boyle's law to explain why this is done.
