with closed end up: volume of air = v1 = 20 x A, cm3, where a = c/s area and pressure = p1 = 75 - 10 = 65 cm of Hg with closed end down: volume of air = v2 = L x A, cm3 where L = length of air column, in cm., pressure = p2 = 75 + 10 = 85 cm of Hg temp remaining constant, during the process, p1.v1 = p2.v2 gives, 65 . 20A = 85 . LA i.e., L = 15.3 cm _____________ if u like, pls Rate my post ! |
