# Phase Diagram

A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions at which thermodynamically distinct phases can occur at equilibrium. In mathematics and physics, "phase diagram" is used with a different meaning: a synonym for a phase space.

### Famous quotes containing the words diagram and/or phase:

If a fish is the movement of water embodied, given shape, then cat is a diagram and pattern of subtle air.
Doris Lessing (b. 1919)

I had let preadolescence creep up on me without paying much attention—and I seriously underestimated this insidious phase of child development. You hear about it, but you’re not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.
Susan Ferraro (20th century)
