A 5.00 L sample of helium at STP expands to 20.0 L. What is the new pressure on the gas?

  • Dejanras: Answer is: the new pressure on the gas is 0.25 atm or 25.33 kPa.
    Boyle's Law: the pressure volume law - volume of a given amount of gas held  varies inversely with the applied pressure when the temperature and mass are constant.
    p
    ₁V₁ = p₂V₂.
    1 atm · 5.00 L = p
     · 20.0 L.
    p
    ₂ = 1 atm · 5 L ÷ 20.0 L.
    p₂ = 0.25 atm, but same amount of helium.
