If the pressure on the syringe is increased to 22.1 psi , but the temperature remains constant, what is the volume of the oxygen gas in the syringe? A sealed syringe contains 6 cc of oxygen gas under 14.7 psi of pressure.
Homework Answers
At constant temperature we can apply Boyle's law PV = constant
P1 = 14.7 psi = 1.0 atm; P2 = 22.1 psi = 1.5 atm; V1 = 6 cc = 6 mL = 0.006 L, V2 = ?
P1V1 = P2V2, V2 = (P1V1) / P2 = (1.0 atm x 0.006 L) / 1.5 atm = 0.004 L = 4 mL = 4 cc
Answer: 4 cc
