    States of matter: TEAS Practice Question with Answer & Explanation

    An original TEAS 7-style science practice question, written for nursing-school applicants — with a full breakdown of every answer choice.

    Question

    What phase change occurs when a gas becomes a liquid?

    • A.Sublimation
    • B.Vaporization
    • C.Condensation
      Correct
    • D.Melting

    Correct answer: C. Condensation occurs when gas particles lose energy and enter the liquid state.

    Why C is correct

    Condensation occurs when gas particles lose energy and enter the liquid state.

    TEAS skill review

    This question tests states of matter, a concept that can appear in the TEAS science section. Read the prompt carefully, identify the rule or evidence being tested, and eliminate options that do not directly satisfy it.

    Why the other choices are incorrect

    The remaining choices conflict with the relevant fact, calculation, language convention, or passage evidence. Check every option against the exact wording of the question rather than choosing an answer that is only generally related to the topic.

    Quick study tip: Condensation is the reverse of vaporization.
