Difficulty: Easy
Correct Answer: Solid
Explanation:
Introduction / Context:
This analogy involves basic states of matter. Melt describes a physical process that converts a solid into a liquid. The question asks for the corresponding state produced by the process Freeze. It checks understanding of everyday physical changes.
Given Data / Assumptions:
1) Melt is the process by which a solid changes into a liquid on heating.
Concept / Approach:
The first pair is Process : Resulting state. When a substance melts, it becomes a Liquid. When a substance freezes, it typically becomes a Solid. Among the options, Solid is the general state, while Ice is a specific example of frozen water, and Condense and Crystal describe other processes or structural forms.
Step-by-Step Solution:
Step 1: Identify the relationship. Melt is a process, and Liquid is the state reached after melting.
Step 2: Recognise that Freeze is a process that turns a liquid into a more ordered state at lower temperature.
Step 3: The general state reached after freezing is a Solid.
Step 4: Ice is an example of a solid form of water but not the general term for the state reached by all liquids.
Step 5: Therefore, the correct parallel is Freeze : Solid.
Verification / Alternative check:
Rephrase both pairs. A substance when it melts becomes a Liquid. A substance when it freezes becomes a Solid. This pattern is symmetric and general. Condense refers to gas turning into liquid, which does not match freezing. Crystal refers to one kind of solid structure, not every frozen product. Ice is specific to water, while the question clearly deals with generic states.
Why Other Options Are Wrong:
Condense is a process rather than a state, and it involves a gas to liquid change. Ice is an example of a solid, not the category itself. Crystal describes a structural arrangement found in many solids but not all, and it is not the direct name of the resulting state. Solid is the only answer that stands parallel to Liquid as a broad state of matter.
Common Pitfalls:
Many students choose Ice because they associate freezing directly with water and ice in daily life. However, in an analogy, especially with Melt : Liquid, the exam expects a broad category, so you must think in terms of states of matter rather than specific substances. This awareness helps you select Solid instead.
Final Answer:
Hence, the correct completion of the analogy is Freeze : Solid, just as Melt : Liquid. The correct answer is Solid.
