What is the degree of freedom for a system comprising liquid water equilibrium with its vapour?
Answer: Option 2 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)...
