Question
Chapter 4, Problem 4A.3BE
Interpretation Introduction
Interpretation: The maximum number of phases that can be in mutual equilibrium in a four component system has to be stated.
Concept introduction: Four component system is a system involving two pure substance in different phases. The system is defined by a set of variables and the minimum number of variable used to define the system is called its degree of freedom. The degree of freedom is a positive quantity and cannot be negative.
