Process and State Variables (PSV)

Process and State Variables

Describing and analyzing processes requires that you can understand, calculate, and manipulate both process data as well as state variables.

How would you calculate process variable values from measurements ?

Certain calculations require you to know quite a bit about the "state" of a material(i.e., its state of aggregation(phase), temperature, pressure, chemical composition, etc.).How can we quantify properties about a material 's state?
