The volume V of a gas varies inversely as pressure P is exerted. If V = 4 liters when P = 3.5 atmospheres, find V when P = 2.5 atmospheres. Note: Round your answer to the nearest thousandth.

  • math - ,

    "The volume V of a gas varies inversely as pressure P is exerted" -->
    v = k(1/p) , where k is a constant

    given:
    when v=4, p=3.5
    4= k/3.5
    k = 4(3.5) = 14

    v = 14/p
    plug in p = 2.5 to find v
