I don't think Boyle's law applies if the amount of material changes. I would think the ideal gas law should be applied instead. PV=nRT (n = number of moles, R = gas constant, T = temperature).i dont know...boyles law states P x V = constant....and i dont know what the pressure is
Strictly speaking you should consider using the Ideal Gas Law PV = nRT.Should Boyle's Law be used in this problem, since the temperature remains constant:
What is the volume of an ideal gas at 1 atm, 12 L, and 25 degrees Celsius if the pressure is decreased to 0.8 atm at 25 degrees Celsius?
