What is phase transition?

  1. Oct 11, 2006 #1
    Hi,

    I was wondering, what actually are phase transitions such as fusion or evaporation? I know thermodynamic definitions such as points where the Gibbs energy is non-analytic or heat capacity changes abruptly, but these say nothing about mechanism. Why does a substance suddenly change its characteristics radically? Thanks.
