  • Q2
    Suppose gas molecules inside a box are held at the same temperature. As the volume of the box increases, the pressure _____
    decreases
    increases
    stays the same
    not enough information

  • Q3
    Bernoulli's Principle States
    the buoyant force is equal to the volume of air displaced
    as the speed in fluid increases, the pressure increases
    as the speed in fluid increases, the pressure decreases
    as the speed in fluid decreases, the pressure decreases

  • Q4
    The upward force exerted between different air pressures is known as
    Lift
    Eddies
    Boyle's Law
    Streamlines
    30s
  • Q5
    Boyle's Law States
    P1V2 = P2V1
    V2/P2 = P1V1
    P1V1 = P2V2
    P1/V1 = P2/V2

  • Q14
    Using Boyle's Law - if the pressure of a gas is tripled, the volume will
    doubles
    decrease to a third of its original value
    also triple in value
    1/9 of its original volume
