Phase Rule topics include: Gibbs phase rule, phase rule applications, uses and its limitations, phases, components, one and two component systems. The phase rule is a general principle in thermodynamics that governs "pVT" systems. These systems are described by the variables of pressure, volume (V), and temperature, in thermodynamic equilibrium. The phase rule is a statement of the number of independent degrees of freedom, F , available to any chemical system defined by a number of mineral phases, M , and molar fractions, r C , of C chemical components. F can be defined for any system... Show more Phase Rule topics include: Gibbs phase rule, phase rule applications, uses and its limitations, phases, components, one and two component systems. The phase rule is a general principle in thermodynamics that governs "pVT" systems. These systems are described by the variables of pressure, volume (V), and temperature, in thermodynamic equilibrium. The phase rule is a statement of the number of independent degrees of freedom, F , available to any chemical system defined by a number of mineral phases, M , and molar fractions, r C , of C chemical components. F can be defined for any system depending on the constraints on M and on r C . The phase rule is expressed as: F = C - P + 2 f + p = c + 2 Here, F is the number of independent degrees of freedom, C is the number of components in the chemical system, P is the number of phases, f is the number of degrees of freedom in the pressure–temperature–composition space, and p is the number of phases. For a one-component system with one phase, the number of degrees of freedom is two. This means that any temperature and pressure, within limits, can be attained. A phase can be gaseous, liquid, or solid. It is perfectly homogeneous and distinct from every other phase that is present in the system. Show less

The phase rule is expressed as: F = C - P + 2 f + p = c + 2
Here, F is the number of independent degrees of freedom, C is the number of components in the chemical system, P is the number of phases, f is the number of degrees of freedom in the pressure–temperature–composition space, and p is the number of phases.
For a one-component system with one phase, the number of degrees of freedom is two. This means that any temperature and pressure, within limits, can be attained. A phase can be gaseous, liquid, or solid. It is perfectly homogeneous and distinct from every other phase that is present in the system.
