  1. 1.

    A student sets up an experiment as shown in the diagram. After some time, the particles are spread evenly throughout both containers. What is this process called?

    A.

    Evaporation

    B.

    Diffusion

    C.

    Condensation

    D.

    Sublimation

  2. 2.

    How does increasing the temperature affect the rate of diffusion of a gas?

    A.

    The rate decreases because particles become heavier.

    B.

    The rate stays the same as temperature only affects volume.

    C.

    The rate increases because the kinetic energy of the particles increases.

    D.

    The rate decreases because there are more collisions between particles.

  3. 3.

    In which state of matter does diffusion occur at the fastest rate?

    A.

    Gases

    B.

    Liquids

    C.

    Solids

    D.

    Diffusion occurs at the same rate in all states

    A.

    Particles lose kinetic energy.

    B.

    Particles gain kinetic energy to overcome some attractive forces.

    C.

    Particles lose potential energy.

    D.
