Gibb's Phase Rule is written as:

F = 2 - P + C
where F = degrees of freedom, P = number of phases, and C = number of independent components. The following shows the number of degrees of freedom of each item. Identify
what
and
how many
phases and independent components are present in each item.

• Solid sucrose and aqueous solution of sucrose and ribose [DOF = 3]
• An aqueous sucrose solution and water vapor [DOF = 2]
• Solid sucrose, aqueous sucrose solution, and water vapor [DOF = 1]
