Alternate Definitions for phase diagram

Definition: A graphical representation showing the stable phases of a material as a function of variables such as temperature, pressure, or composition.

Example: The phase diagram for water shows how its state changes from solid, to liquid, and to gas as temperature and pressure are varied

Definition: A measure of a material's resistance to elastic deformation under tensile or compressive stress.

Example: The Young's modulus of rubber is low, signifying its high elasticity and tendency to return to its original shape after being stretched.
