If the volume of gas is increased to 400 cubic meters, the pressure will be

**drwls**, Friday, May 25, 2012 at 3:31amAt constant temperature (which is what they want you to assume),

P*V = constant

125*20 = 400*P2

P2 = final pressure = (125/400)*20

= 6.25 psi

Since the equation

P1/P2 = V2/V1

involves dimensionless ratios, I did NOT have to convert pressure from psi to Pascal units and back again. I chose to keep pressure in psi and volume in cubic meters
