    What is different between colloid and suspension?

    Also,
    define what is meant by
    1.brownian motion-The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Brownian motion (named after the Scottish botanist Robert Brown) is the seemingly random movement of particles suspended in a fluid (i.e. a liquid or gas) or the mathematical model used to describe such random movements.

    2.tyndall effect-Visible scattering of light along the path of a beam of light as it passes through a system containing discontinuities, such as the surfaces of colloidal particles in a colloidal solution.

    Do you think are these two words are correct for chemistry class definition?
