When three of the phases of a two component system are simultaneously in equilibrium the number of degrees of freedom is

Concept:

• Phase of a system is defined as the physical state that can be separated from other part of system mechanically.
• Components are distinct constituents that are independently variable.
• In a system, minimum number of independently variable factors that can be used to define the system gives degree of freedom (F). The factors can be pressure, temperature , or composition/concentration.

Degree of Freedom(F) = C- P+ 2

C is the number of components of system

and P is the number of phase

Explanation:

For given system, number of components, C = 2

number of phase, P = 3

Degree of freedom, F should be

\(F= C-P+2 \)

\(F=2-3+2 \)

\(F=1 \)

Conclusion:

Hence, the degree of freedom of a two component system with its  3 phases in simultaneous equilibrium is 1
