Question

If the temperature is constant, the pressure of a gas in a container varies inversely as the volume of the container. If the pressure 60 pounds per square foot in a container with 9 cubic feet, what is the pressure in a container with 4.5 cubic feet

Answer 1

P₁ = 60 psf

V₁ = 9 ft³

P₂ = ?

V₂ = 4.5 ft³

 

P₁V₁ = P₂V₂

 

P₂ = P₁V₁ / V₂ = ( 60 psf)(9 ft3) / ( 4.5 ft3) = 120 psf
