2004PPp1q15 - Volume of bubble at bottom of lake (P1V1 = P2V2)

Updated: Oct 23


Answer: Option A


Since the air bubble is enclosed, PV at A is equal to PV at B.

                  PAVA = PBVB

(Patm + Pwater) VA = (Patm) VB

         (10 + 20) VA = 10 x 6

                       VA = 60 / 30

                            = 2 cm3
