Question

for one component system the phase rule is​

Answer 1

The phase rule states that F = C − P + 2. ... Thus, for a one-component system with one phase, the number of degrees of freedom is two, and any temperature and pressure, within limits, can be attained.

Answer 2

Answer:

The phase rule states that F = C − P + 2. Thus, for a one-component system with one phase, the number of degrees of freedom is two, and any temperature and pressure, within limits, can be attained.

Explanation:

The phase rule is a law relating variables of a system in thermodynamic equilibrium that is deduced by the American physicist J. Willard Gibbs in his papers on thermodynamics. Systems in thermodynamic equilibrium are generally considered to be isolated from their environment in some kind of closed container. The variables are the number of phases (P), the number of chemical components (C), and the number of degrees of freedom (F) of intensive variables, such as temperature, pressure, and percentage composition. For one component and three phases (e.g., ice floating in water with water vapour above it, in a closed container), there is no degree of freedom, and temperature and pressure are both fixed at what is called the triple point.

The phase rule states that F = C − P + 2. Thus, for a one-component system with one phase, the number of degrees of freedom is two, and any temperature and pressure, within limits, can be attained.
