Homework Help: Entropy Changes

  1. Oct 27, 2007 #1
    entropy increases? entropy decreases ? no change in entropy?

    diffusion, evaporating, mixing, melting, separation

    i think

    diffusion - increase

    evaporation - increase

    mixing - increase

    melting - increase

    but what about separation :S?


    and if anyone thinks any others are wrong do tel me :)

    Looks good. When you separate something, you are taking something that is mixed and creating two or more pure things. Does this represent an increase or decrease in organization (order)?
