Question

1. A cylinder fitted with a piston contains 14 L at a pressure of 7.5 atm. The entire contents of the cylinder

are forced into a tightly folded plastic bag at a pressure of 1 atm. What will be the new volume of the bag
when filled by the escaping gas?

Answer 1

V₂ = 103.6 L

Step-by-step explanation:

Given data:

Initial volume = 14 L

Initial pressure = 7.5 atm

Final pressure = 1 atm

Final volume = ?

Solution:

Formula:

According to Boyle's law,

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = 7.4 atm× 14 L / 1 atm

V₂ = 103.6 atm. L / 1 atm

V₂ = 103.6 L
