Answer:
Perfectly Specified
Explanation:
Pressure, P = 0.9 atm
Boiling point = T
Number of components C = 1
Number of phases P = 2
Using Gibbs phase rule as:
F = C - P + 2
F = 1 - 2 + 2 = 1
At Pressure = 0.9 atm, boiling point is T which means that the temperature is also fixed which is equal to 96.7 °C . The data taken from steam table.
In given problem, the pressure is fixed so temperature is also fixed.
The system is perfectly specified.
