Click here to go Practice Test section on this topic namely Phase Diagram.
But if you want to read this topic first and then practice it then read it carefully. The Multiple Choice Questions (MCQ) based on the Phase Diagram are given below:
PART - II
1) For binary phase diagram Gibbs phase rule may be given as
Correct Answer is "A"
For binary phase diagram, Gibbs phase rule is F = C – P + 1(here pressure is constant)
2) Once a system is at a state of equilibrium, a shift from equilibrium may result in the alternation of which of the following?
Correct Answer is "D"
Once a system is at a state of equilibrium, a shift from equilibrium may result by the alternation of Temperature, Pressure, and Composition
3) A binary composition – temperature phase diagram for an isomorphous system is composed of regions that contain which of the following phases and/or combination of phases?
Correct Answer is "D"
A binary composition – temperature phase diagram for an isomorphous system is composed of Liquid, α, and Liquid + α regions
4) Which of the following is an example of a 2 component 1 phase system?
Correct Answer is "C"
Brine is an example of a 2 component 1 phase system
5) Ice water is an example of
Correct Answer is "B"
Ice water is an example of 1 component 2 phase system (H20 is the only component and solid(ice) and liquid(water) 2 phases present.
6) The solubility of sugar in water
Correct Answer is "D"
The solubility of sugar in water Increases with an increase in temperature
7) What are the external variables that affect the phase structure?
Correct Answer is "A"
Temperature and Pressure are the external variables that affect the phase structure
8) What is the phase fraction of an alloy when it is one phase system?
Correct Answer is "D"
The phase fraction of an alloy when it is one phase system is 1.0
9) Which of the following remains constant in Unary phase diagrams?
Correct Answer is "C"
Composition remains constant in Unary phase diagrams
10) What is a triple point?
Correct Answer is "B"
At the triple point, all three states are in equilibrium
