Fire Heat Analogy Explained

This question tests your ability to understand and apply analogies. An analogy presents a relationship between two words (a pair) and asks you to find another pair where the same relationship exists. The given pair is Fire : Heat.

Analyzing the Fire: Heat Relationship

Let's figure out the connection between Fire and Heat:

• Fire is a process involving rapid oxidation, typically producing heat and light.
• Heat is a common and direct result or product of Fire. Fire generates heat.

So, the relationship is: "A causes/produces B" or "B is a primary characteristic/product of A".

Applying the Relationship to Friction

Now, we need to find a word that has the same relationship with Friction. We are looking for something that is a primary product or result of Friction.

Evaluating the Options

Let's examine each option in the context of Friction:

• Temperature: While friction often increases temperature, 'Temperature' itself is a measure, not the direct product in the same sense heat is from fire. Heat is the energy transfer that causes temperature changes.
• Motion: Friction opposes motion. Motion can cause friction, but friction doesn't primarily produce motion; it tends to stop or slow it down.
• Burn: Burning is a type of combustion (like fire), often involving heat. It's not a direct product of friction itself.
• Energy: When surfaces rub together (friction), mechanical energy is converted into thermal energy, which we perceive as heat. Therefore, Energy (specifically thermal energy) is a direct product or result of Friction, similar to how Heat is a product of Fire.

Conclusion

The relationship "A produces B" holds true for Fire : Heat. Applying this to Friction, we find that Friction produces Energy (often in the form of heat). Therefore, Energy is the word that shares a similar semantic relationship with Friction.
