Question

The volume, V, of a gas varies inversely as the pressure, P, on the gas. If the volume of a gas is 12ft^3

when the pressure is 20lb/ft^2 , find the volume of the gas when the pressure is 14lb/ft^2

Answer 1

17.14 ft³

Step-by-step explanation:

Use Boyle's Law to solve this.

PV = k (k is a proportionality constant)

k = (20 lb/ft²)(12 ft³) = 240 lb·ft

V = k/P = 240 lb·ft / 14 lb/ft² = 17.14 ft³
