Deposition is the process by which gas transforms from a state of liquid directly into one of solid. In Earth science, deposition instead of state change refers to the dropping of sediments by wind or water. What happens during deposition is that the gaseous substance is deposited directly, skipping the intermediary liquid state, typically as crystals. A compound can be divided into pure samples of each of its chemical components using the deposition process. Let’s discuss the deposition process example in detail along with answering the question- is dry ice sublimation or deposition?
1. What is the Process of Deposition?
The deposition is the procedure that skips the liquid phase and transforms a gaseous state directly into a solid state. It is a thermodynamic process and is also called desublimation.
The method of adjusting the pH of the solution is used for the deposition process on an industrial scale. The principal phases of the deposition process are:
- When molecules are disseminated in a solution or gas phase, they will create a new link in the form of crystal seeds that are just a few nanometers across.
- The seeds are conditioned by managing and making them larger and more stable by adjusting the temperature, degree of saturation, pressure, and so on.
2. What happens during Deposition?
The molecules must be made to lose their heat energy before they can start to slow down and assemble. A deposition process example is a frost that forms on a car’s windows on an extremely frigid day. During the deposition phase, change takes place either by applying pressure or without it directly. The gaseous matter is converted to solid matter with the help of its surroundings.
This is what happens during deposition. This makes us wonder — is dry ice sublimation or deposition? And what are their other examples in daily life? (See What is the Greatest amount of Heat when warming 100 grams of Ice?)

- For instance, ice crystals are formed on surfaces that are extremely cold when warm, moist air is in contacts with them, such as the ground or things on it. Most people refer to these ice particles as frost.
- The primary mechanism behind the blockage of the lungs brought on by inhaled contaminants is also deposition. For instance, the tar-like buildup found in the lungs of COPD patients is caused by the deposition of cigarette smoke.
- Ignition is caused by a chemical interaction between fuel and oxygen. Black soot formation is inversely correlated with machine workload.
- Various industries emit nitrogen and sulfur oxide wastes into the atmosphere, where they are changed into nitric and sulfuric acid. These compounds either fall to the ground as solid particles (dry deposition) or along with rain or snow.
- To create anti-reflective properties, optical lenses are coated with magnesium fluoride.
Iodine is also a deposition process example which is a physical change of matter and is also present in the human body. Must read Boiling of Water is a Physical Change or Chemical Change?
4. What is a Deposition Process Example?
In the paragraphs above, we read a few instances of deposition, which only occur during the deposition procedure. Deposition procedures are therefore comparable.
For instance, water vapor in the air turns into small ice crystals when it comes into contact with a window pane that is both icy cold and warm inside a house. On the glass, the ice crystals are deposited, frequently in lovely designs like leaves on the window. This is a deposition process example. (See 12 Facts about Fog Breath)
5. What is an Example of Sublimation and Deposition?
An example of sublimation and deposition is well-known Solid Carbon Dioxide, which is nothing but dry ice. It is common for pharmaceutical bottles to advise storage at room temperature or in a cold environment. This is due to the potential for some of the components to sublimate if they are heated up excessively.
Spraying sulfuric acid into the reaction container, which is already filled with ammoniac gas, results in the formation of dry ammonium sulfate powder. All of the water in the system will evaporate due to the heat created by the reaction, which will then result in salts that resemble flour. This is nothing but a deposition.

6. Is Snow an Example of Deposition?Photo By Simon On Pixabay
Yes, as water vapor builds up in the atmosphere, it will eventually reach the condensation point, where the temperature causes the gas to solidify and the cloud to form with less mass than the surrounding air.
Because the cloud’s capacity is already at capacity, the water vapor breaks. One of the natural phenomena that take place in the troposphere is called rain if the breaking is in the form of water particles cascading towards the land. Additionally, it will turn into snow if the temperature falls below 0 degrees Celsius. (See How Fast does Rain melt Snow?)
7. Is Hail an Example of Deposition?Photo By Maraisea On Pixabay
Yes, hail is a deposition process example as it is formed when there is a phase change. Hail creates havoc all around and is a result of layers of ice growing larger.
Convective storms can produce hail as a form of precipitation. Both the dry and wet processes can be used to grow hail. Deposition on the hailstone triggers the dry process. When it deposits on the hailstone, the water vapor immediately transitions to the ice state. Must see Which Best Describes the Dissolving Process?
8. What is Water Deposition?
Deposition happens when precipitation, composed of evaporating water vapor, returns to the earth. This water may run off and return to various bodies of water, including lakes, rivers, ponds, and seas. It may also land on the ground and mix with the groundwater.
When humid air is chilled below the dew point without condensation forming naturally, the result is supercooled water vapor that instantly freezes when it comes into contact with a cold surface. And the outcomes are breathtakingly lovely! (See What Happens When Water Boils?)
9. Is Dry Ice Sublimation or Deposition?
Dry ice is created from carbon dioxide through deposition as well. The temperature and pressure of a chamber containing carbon dioxide gas are altered. A solid will form when gaseous carbon dioxide reaches 5.1 atm and -79°C.
The distinctive fog effect of dry ice is created by the sublimation of carbon dioxide back into gas. Dry ice is formed from sublimation and is used to keep things cool. But dry ice before sublimation goes through a deposition process and becomes dry ice. (See How does Radiation Fog develops in the Valley at Night?)
10. What are 3 Examples of Sublimation?Photo by Neven Krcmarek on Unsplash
Sublimation is a chemical procedure that skips the liquid phase and converts the solid immediately into gas. This occurs as a result of the substance absorbing extra energy from its immediate environment. When air pressure is low at higher elevations, sublimation occurs more frequently.
- Typically, naphthalene can be found in pesticides like mothballs. At a temperature of 176 °F, naphthalene sublimates and produces vapors. It destabilizes chilly surfaces to produce crystals that resemble needles.
- The procedure makes use of sublimation science. The sublimation dyes are transferred into the substrate at the molecular level using a unique combination that the heat press uses, and that might vary depending on the substrate.
- The inverse sublimation of the gases produced in supernovas, whose final pressure and temperature may drive them to become solid matter, is responsible for the development of solid matter in planets and other celestial objects.
Both processes are opposite of each other, and we understand this by the sublimation and deposition process example in the previous section of this article. They involve changes in states of matter and the formation of new compounds. (Also read How Long Does Gas take to Evaporate?)
