Question

Question 4 of 11 > A scuba diver ascends too quickly and develops the bends. A nitrogen bubble has formed in the patient's elbow. At a depth of 53 ft, where the pressure is 2.60 atm, the bubble had a volume of 0.022 mL. Assuming a constant temperature and number of moles of nitrogen in the bubble, what volume did the bubble increase to at the surface, where the pressure is 1.00 atm? bubble volume at surface: ml The scuba diver is placed into a hyperbaric oxygen chamber where the pressure is 3.50 atm. What is the volume of this same nitrogen bubble while the patient is in the hyperbaric chamber? bubble volume in chamber:

Answer 1

-------- at depth. --- Pressure, pl = 2.60 atm Volume. Vi = 0.022 me at surface Pressure P2 = atm Volume Vz = ? . dan According to Boyle's Law.. Pivo = P2 V2

V2 = Pive V2 = 2.60 X 0.022 | V2 = 0.0572 ml. .. Bubble volume at surface = 0.057 2 12. Conditions in hyperbaric oxygen chamber. P2 = 3.50 atm. Assume VI = V2 (at surface V2 = ? . and P1 = Pz (at surface) So, P = I alm. - No = 0.0572 ml According to Boyle's Law V Plui = P₂ V2 V2 = P. Vi VL 2 1X0.0572 3.50 12 30.0163428571 me ar V2 = 0.0163 me Bubble volume in chamber = 0.0163 me.
