Phase Diagram
- ANS - a graph showing the conditions at which a substance exists as a
solid, liquid, or vapor
a line separates the regions that correspond to the solid and liquid
phases. For most substances, since the solid phase is denser than the
liquid, this line has a positive slope. This indicates that it is possible to
convert the liquid substance into solid by increasing pressure. Since the
opposite is true for water, however, the line between these regions has a
negative - or downward-tilting - slope. This hallmark is one easy way to
distinguish the phase diagram of water from that of most other
compounds.
