Sublimation vs. Deposition: Know the Difference
By Shumaila Saeed || Published on February 28, 2024
Sublimation is the transition of a substance directly from solid to gas, while deposition is the direct change from gas to solid without passing through a liquid phase.
Key Differences
Sublimation is a physical process where a solid changes directly into a gas without passing through a liquid state. Deposition, conversely, is the process where a gas transforms directly into a solid without becoming a liquid first. This fundamental difference lies in the direction of the phase change.

In sublimation, energy is absorbed by the solid to overcome intermolecular forces, allowing the transition to a gas. In deposition, a gas loses energy, leading to the formation of solid structures as atoms or molecules slow down and bond together.

An example of sublimation is dry ice (solid CO2) turning into carbon dioxide gas. For deposition, frost formation on cold surfaces from water vapor is a common example, where the gas turns directly into solid ice crystals.

Sublimation occurs under specific conditions of pressure and temperature, often at low pressures or high temperatures. Deposition usually happens at lower temperatures and under conditions where gas molecules can directly settle as a solid.

The rate of sublimation can be affected by surface area and temperature, while the rate of deposition is influenced by factors like the concentration of the gas and temperature. Both processes are integral in various natural and industrial applications.
