Identifying the Correct Word for Vaporization Tendency

The sentence describes a property of a mixture that is related to its tendency to 'vaporize'. We are told that lowering the temperature reduces this tendency.

Analyzing Word Options

• acerbic: This means sharp or sour in taste or temper. It does not relate to vaporization.
• resilient: This means able to bounce back or recover quickly. It does not fit the context of vaporization.
• volatile: This word describes substances that evaporate easily or change rapidly. This directly relates to the tendency to vaporize.
• heterogeneous: This means diverse or consisting of different parts. While a mixture can be heterogeneous, this term doesn't specifically describe its vaporization behavior.

Connecting Word to Context

The key phrase is "tendency to vaporize". A substance that vaporizes easily is called volatile. The sentence states that lowering the temperature reduces this vaporization tendency, which is characteristic behavior for volatile substances.

Conclusion

Therefore, the most appropriate word to complete the sentence is volatile, as it accurately describes a substance's propensity to vaporize, a property affected by temperature changes.
