Sublimation vs. Deposition: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 7, 2024
Sublimation is the process where a solid turns directly into gas, while deposition is the reverse, where gas turns directly into a solid.
Key Differences
Sublimation is a phase transition in which a solid changes directly into a gas without passing through a liquid phase. Deposition, conversely, is the process where a gas transforms directly into a solid, bypassing the liquid stage.
Sublimation occurs under specific conditions of temperature and pressure, often requiring heat absorption. Deposition happens under conditions where gas molecules lose energy and transition directly to a solid state.
An example of sublimation is dry ice turning into carbon dioxide gas. Frost formation on cold surfaces exemplifies deposition, as water vapor in the air turns directly into ice.
Sublimation is used in freeze-drying and printing industries. Deposition plays a crucial role in manufacturing processes like snowflake formation and thin-film deposition in electronics.
In sublimation, molecular bonding becomes weaker, allowing solids to turn into gas. In deposition, gas molecules slow down, increasing intermolecular attraction, resulting in solid formation.

Sublimation and Deposition Definitions
Sublimation
Sublimation printing involves transferring designs onto fabric or materials using heat.
The custom t-shirts were made using sublimation technology.
Deposition
In legal terms, deposition refers to the sworn testimony of a witness outside of court.
Her deposition was crucial in the court case's outcome.
Sublimation
Sublimation in chemistry involves a solid changing its state to a gas under specific conditions.
Naphthalene balls in wardrobes sublimate, leaving no residue.
Deposition
Deposition in physics involves gas particles forming a thin film on a surface.
In microelectronics, deposition is used to create circuit paths.
Sublimation
Sublimation is the transition of a substance directly from the solid to the gas state.
Dry ice sublimates at room temperature, releasing carbon dioxide gas.
Deposition
Deposition is the phase change from gas directly to solid without becoming liquid.
Snowflakes form by the deposition of water vapor in clouds.
Sublimation
In psychology, sublimation refers to channeling unacceptable impulses into socially acceptable activities.
He used sublimation by redirecting aggressive energy into sports.
Deposition
Deposition in geology is the process of sediment settling and accumulating in a new location.
The river's flow slowed, leading to the deposition of sediments.
Sublimation
Sublimation is used in freeze-drying food, preserving its nutritional value.
The process of sublimation is crucial in making freeze-dried fruits.
Deposition
Deposition in chemistry is the settling of particles or sediment from a solution.
The chemical reaction resulted in the deposition of a precipitate.
Sublimation
To be transformed directly from the solid to the gaseous state or from the gaseous to the solid state without becoming a liquid.
Deposition
The act of deposing, as from high office.
FAQs
