Saturated liquid or the saturated vapor has how many independent variables?

Saturated liquid or the saturated vapor has how many independent variables? Correct Answer 1

Concept:

Gibb's phase rule is given by;

P + F = C + 1

where, P = No of phase, F = Degree of freedom, C = No of  components

Calculation:

Given:

For pure substance (C) = 1, P = 1

1 + F = 1 + 1

F = 1

Therefore, F = 1 shows that only one property is required to be known to fix up the state.
