Sublimation and condensation are two processes in which a substance changes from one state to another. While both processes involve the transformation of a substance, the underlying mechanisms differ.
By understanding the differences between these two processes, we can better understand the properties of matter.
The definition of sublimation
Sublimation and condensation are two processes that are often confused with one another. Sublimation is the direct conversion of a solid into a gas without it becoming a liquid first.
This process is most commonly observed with dry ice, which is frozen carbon dioxide. When dry ice is exposed to the atmosphere, it will evaporate without becoming a liquid first. Condensation is the opposite process, where a gas is converted into a liquid.
This typically happens when the air is cooled to a point where the water vapor it contains can no longer remain in a gaseous state, and condenses into liquid water droplets. Both processes have a role to play in the water cycle, but sublimation is a much less common process.
The definition of condensation
The difference between sublimation and condensation lies mainly in the way the two processes take place. Sublimation is the direct transition of a substance from a solid state to a gaseous state, without passing through a liquid phase.
On the other hand, condensation is the physical process of a gas changing into a liquid. Condensation occurs when molecules in the gas phase lower their energy by releasing it as heat, thus forming a liquid. Sublimation, on the other hand, is the reverse process of condensation, where molecules in the liquid phase gain energy and transition into the gas phase without passing through the solid state.
How sublimation and condensation differ
Sublimation and condensation are two processes that involve a change in a substance’s physical state. Sublimation is the process of a solid substance changing into a gas, while condensation is the process of a gas changing into a liquid.
Sublimation is often seen with substances like dry ice, where the solid form of carbon dioxide will transform directly into a gas. Condensation on the other hand is often seen with water vapor, condensing in the atmosphere and forming clouds or precipitation.
Both processes are important in the natural environment and are widely studied in the fields of chemistry and physics.
Examples of sublimation and condensation
When it comes to the different processes of water in the atmosphere, two of the most commonly talked about are sublimation and condensation. Sublimation is when water vapor turns directly into a solid, while condensation is when water vapor turns into a liquid. The difference between the two is that sublimation occurs when the water vapor is cooled to a temperature below its freezing point, while condensation occurs when the water vapor is warmed to a temperature above its boiling point.
Sublimation is often seen in winter, as water vapor turns into snow or frost. Condensation is seen most often in the summer, when water vapor turns into dew or fog.
Practical applications of sublimation and condensation
Sublimation and condensation are two processes that are often used in everyday life for a variety of purposes. Sublimation is the process of a solid material turning directly into a gas, while condensation is the process of a gas turning into a liquid.
Sublimation is a physical process that involves no intermediate liquid state, while condensation requires the presence of an intermediate liquid state. In addition, sublimation generally occurs at a much lower temperature than condensation.
For example, dry ice, or frozen carbon dioxide, sublimes at -75°C, while water vapor condenses to a liquid at 100°C. Practical applications of these processes can be seen in refrigeration, air conditioning, and the manufacture of certain products such as perfumes, cosmetics, and pharmaceuticals.

Conclusion
In conclusion, the difference between sublimation and condensation is that sublimation is the process of a solid substance turning directly into a gas without first becoming a liquid, while condensation is the process that occurs when a gas turns into a liquid. Sublimation is a reversible process, while condensation is not. Sublimation is more commonly observed in colder climates, while condensation is more common in warmer climates.
