What is the final pressure of a system (atm) that has the volume increased from 0.75 l to 1.1 l with an initial pressure of 1.25 atm? 1.1 0.85 1.8 1.2 none of the above?
Boyle's law states that pressure is inversely proportional to volume of gas at constant temperature PV = k where P - pressure , V - volume and k - constant P1V1 = P2V2 where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation substituting these values in the equation 1.25 atm x 0.75 L = P x 1.1 L P = 0.85 atm final pressure is B) 0.85 atm
