Boyle's Law

  • #1
So i looked up Boyle's and it said

PV = C

P= pressure

V= Volume

C= constant


so my question is

Suppose 38 pounds of books were balanced on a syringe plunger with a cross-section area of 0.45 in^2?

A) how much pressure would just the books exert on the trapped air sample?

so would this be correct

P= 38/0.45= 84.4 psi

im not sure if 38 is the constant or even if im using the right formula for this problem. thanks guys

Well, your answer seems right, but you didn't get it from using the Boyle's Law formula which you quoted.

You simply used Pressure=Force/Area, which is perfectly valid.

Moreover , the boyle's law is only applicable to ideal gases at constant temperature and cannot be applied to objects and particle of classical physics.
