What is the degree of freedom for a system comprising liquid water equilibrium with its vapour?
A. 0
B. 1
C. 2
D. 3
Answer: Option B
Solution (By Examveda Team)
Given, vapor-liquid equilibrium :Number of components \[\left( {{\rm{water}}} \right) = 1\]
Number of phases involved \[\left( {{\rm{vapor - liquid}}} \right) = 2\]
So, degree of freedom :
\[\begin{array}{l} \left( f \right) = C - \emptyset + 2\\ 1 - 2 + 2 = 1 \end{array}\]
