How Does Boyle's Law Apply to a Bicycle Pump and Tire System?

[LadyDiana1011]

A bicycle pump contains 200 cm³ o fair and is connected to a bicycle tyre.
The volume of the tyre is 800 cm³. The pressure of the air in the tyre (it is `flat´) is 1.0 atmosphere, the same as the air initially?
A) What is the total volume of the air initially? (=volume1)
B) What is the volume of air after the pump is pushed in? (=volume2)
C) What will be the pressure in the tyre then?


Can you please give me the answers?
If possible explain it?
Would be nice of you.
Thankyou!

Diana

Diana,

Sorry, but PF rules discourage "giving answers". Plus, where is the fun in that? We do, however, answer questions related to your problem solving process. Go ahead and attempt a solution--if you are confused about something, say so.
