Question

A large research ballon whose volume is 450m^3 is to be filled with helium at atmospheric pressure. The helium is stored in cylinder of volume 0.05 m^3 at a pressure of 30 atm. How many cylinders are required?( assume the temperature constant)

Answer 1

using boyles law:

Constant temp. implies that PV=constant. So you can say ( P initial ) (V initial)= (P final) (V final)

Answer 2

( x 0.05m^3) (30atm) = (450m^3)(1atm) where x is the number of cylinders of volume 0.05m^3. Thus, you want to solve for x.

Answer 3

thank you
