What is the phenomenon of change of state from solid to gas without passing through liquid?

Last Updated: 25 Jun 2026

What is the phenomenon of change of state from solid to gas without passing through liquid? The most useful approach is to identify the physical quantity, phenomenon, law, or device named in the stem and connect it with its standard definition. Here, the relevant answer is “Sublimation.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. Physics explains measurable natural events through quantities, units, observations, mathematical relations, and experimentally verified laws. The distractors in this question—Evaporation, Condensation, Vaporization—do not satisfy the exact condition stated. The final selection must agree with the explanation and marked answer: Sublimation.

AEvaporation

BCondensation

CSublimation

DVaporization

Correct Answer: SublimationYour Answer: C

Explanation

— the scientifically appropriate response is Sublimation. Option-wise review: Sublimation is correct under the condition given in the stem. Evaporation is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Condensation is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Vaporization is incorrect because it fails the governing relation or characteristic relevant to this case. Therefore, option C, Sublimation, is factually and logically consistent with the question. Sublimation is the direct change from solid to gas phase without passing through liquid.

Important Notes

Physics answers are condition-dependent. The same lens, force, circuit, wave, or thermodynamic system can behave differently when distance, medium, temperature, direction, or boundary conditions change. Preserve every qualifier in the question.
Eliminate Evaporation, Condensation, Vaporization here because none fulfils the exact requirement of the stem. The final answer and correct-index field must point to option C.
Exam memory point: connect Sublimation directly with the key wording of the question, then verify it once against the relevant definition or formula before marking the answer.Examples: dry ice camphor iodine

FAQ

SSC CGL Physics FAQs

Common questions and clear answers for this topic.

How many physics questions usually appear in the SSC CGL exam?

Physics typically makes up a small portion of the General Science questions, usually focused on concepts rather than numerical problems.

Which physics topics are most important for SSC CGL?

Basic mechanics, heat, sound and light, and electricity and magnetism are the areas that come up most consistently across previous papers.

Do I need to solve numerical problems for SSC CGL physics?

Rarely. Most questions are conceptual and test everyday understanding rather than calculation skills.

Is NCERT physics enough for SSC CGL preparation?

NCERT textbooks from classes 9 and 10 build a strong enough conceptual base for most of what SSC CGL asks.

How can I make physics concepts easier to remember for SSC CGL?

Connecting concepts to everyday observations, like why a thermos keeps tea warm, makes them far easier to recall than memorizing definitions.
