Which of the following phase diagram shows liquid immiscibility ?
Eutectic
Peritectic
Monotectic
Eutectoid
None of these
To determine which phase diagram shows liquid immiscibility, we need to understand what liquid immiscibility means. Liquid immiscibility is the property of two or more liquids not being able to mix or blend together, resulting in the formation of separate liquid phases.
By analyzing the given options:
1. Eutectic: The eutectic phase diagram represents a specific compositional point where a mixture of two or three components forms a eutectic mixture, which is a solid compound that melts at a lower temperature than any of its individual components. It does not depict liquid immiscibility.
2. Peritectic: The peritectic phase diagram shows a phase transformation that occurs when a solid phase and a liquid phase react to form a new solid phase. It does not represent liquid immiscibility.
3. Monotectic: The monotectic phase diagram represents a system where a liquid phase splits into two separate liquid phases upon cooling. This indicates liquid immiscibility and is the correct answer to your question.
4. Eutectoid: The eutectoid phase diagram represents a specific compositional point where a solid phase transforms into two different solid phases upon cooling.
Therefore, the correct answer to the question is "Monotectic." This phase diagram demonstrates liquid immiscibility.
