Desublimation

Gas to solid without liquid intermediate.

Short definition

Gas to solid without liquid intermediate.

Full explanation

Desublimation in the context of liquids solids phase changes: Gas to solid without liquid intermediate. In practice this means relating macroscopic observation (mass, pressure, color), particle-level picture (atoms, electrons, ions moving and rearranging), and symbolic representation (formulas, equations, units). For Desublimation, students connect the definition to linked lessons: do not just memorize the phrase — predict what changes when conditions change and check with dimensional analysis.

Notation and units

• Notation: —
• Common units: SI or derived, temperature in kelvins when in gas/energy contexts.
• Symbolic hint: See related formula if applicable.

Example

Example for desublimation: In a worked problem where this term appears, substitute measured values with correct units and check that the dimensional result matches the intended quantity. For instance, calculating a desublimation often uses the form $n=m/M$ or $c=n/V$ or $PV=nRT$ with $T$ in kelvins — illustrating how desublimation leads to a numerically different but dimensionally correct result when units are handled.

Confused with

• Sublimation — distinction: Desublimation is gas to solid without liquid intermediate. while Sublimation has a different defining property. See cross-link in glossary.
