Algebra II

The volume of a gas in cubic centimeters, V, varies inversely with the pressure of the gas in liters per square centimeter, p.

When the volume of the gas is 16 cm3, its pressure is 20 L/cm2. Find the volume of the gas when the pressure is 2.2 L/cm2.

  1. V = k/P, so
    VP = k, a constant

    so, you want V so that

    2.2V = 20*16

    By the way, L/cm^2 is not pressure. 1L = 1000cm^3, so L/cm^2 = cm

    Pressure is force/area, as in N/m^2

    I've never heard of this L/cm^2 unit. But then, I'm not a physicist...

  2. What is an L ?? Perhaps a Newton??? if cm^2/then D for Dyne

    anyway

    v = k/p

    16 cm^3 = k / 20L/cm^2
    k = 16*20

    v = 16*20/2.2 = 145 cm^3

  3. so the answer would be v=145.45
