Homework Answers
In a phase diagram, liquidus line is defined as the line or boundary that separates the liquid phase from the solid + liquid phases.
Solidus line is defined as the line below which the solution is completely solid.
Thus the point in a liquidus line represents the equilibrium of the phase of liquid and liquid + solid.
Solidus line represents the equilibrium between solid phase and solid + liquid phase.
An isomorphous phase diagram is shown below and liqidus and solidus are identified.

What does the triple point on a phase diagram represent? Select one: a. It represents the conditions under which a substance can exist in two of the three phases in stable form. b. It represents the point at which the distinction between liquid and gas phases becomes unclear. c. It represents the conditions of pressure and temperature under which solid, liquid, and gas all co-exist. d. It represents the point at which the substance undergoes sublimation.

A binary phase diagram of material A and material B with 36.4 weight %B is at a temperature where both solids and liquids are present. If the intersection with the liquidus line (on the left) at this temperature is 5.3 weight %B and the intersection with the solidus line (on the right) is 70.1 weight %B, determine the amount of solid present in the liquid solid combination in %. Answer in % without the symbol.
