Sublimation is the process through which a solid goes directly to a gas, skipping the liquid state.
Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.
What is sublimation and its examples?
Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.
What are 3 examples of sublimation?
To help you gain a better understanding of this process, here are some real-life examples of sublimation:
- Dry Ice. As mentioned earlier, dry ice is one of the most popular examples of sublimation in real life.
- Specialized Printers.
- Moth Balls.
- Freeze Drying.
- Air Fresheners.

How is sublimation used in everyday life?
There are many examples of sublimation in daily life: The air fresheners used in toilets. The solid slowly sublimes and releases the pleasant smell in the toilet over a certain period of time. Moth balls, made of naphthalene are used to drive away moths and some other insects.31 Aug 2016
What is sublimation write two examples of sublimating substances?
Iodine is another example of a substance that undergoes sublimation. It’s a silver-gray solid that gives off a purple gas. Water can undergo sublimation under some atmospheric conditions. For example, snow produces water vapor without melting when the air is very cold and dry.
What is a real life example of sublimation?
Examples of Solid to Gas (Sublimation)
Dry Ice – Solid carbon dioxide is known as “dry ice” and sublimates at room temperature. Freeze-drying – Water can be sublimated in a food product by using a vacuum.
What things go through sublimation?
These are some common substances that undergo sublimation upon heating under the normal atmospheric pressure condition.
- dry ice (solid CO2, carbon dioxide)
- Ice & snow ( from Water )
- iodine crystals.
- Naphthalene (mothballs) Naphthalene – Wikipedia.
- Caffeine ( under vacuum )
- Phthalic Anhydride.
Is Iodine an example of sublimation?
Iodine provides an excellent example of sublimation. When iodine sublimes it forms a visible purple gas. When the gas cools it returns directly to the solid phase, an example of deposition.14 Oct 2014
What is the basic principle of sublimation?
Sublimation is a process in which a solid turns directly into gas without passing into liquid state. It works on the principle that solids have a weak intermolecular force hence a higher vapour pressure which converts it into directly vapour state.4 Aug 2016
What is opposite of sublimation?
Sublimation is the transition from the solid to the gas state. A good example is carbon dioxide ice. The opposite of this process is called deposition : the transition from the gas to the solid. Condensation is the transition from gas to liquid as in the condensation of steam to liquid water.
What is an example of solid to gas?
Some examples of this process are the following: Dry ice is a solid made from carbon dioxide gas undergoes sublimation thus there is no remnants of liquid form. Solid car air fresheners hanged inside cars change directly into vapor without melting.
What is sublimation with diagram?
Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.2 Jun 2018
Is dry ice an example of sublimation?
Sublimation and the water cycle:
“Dry ice” is actually solid, frozen carbon dioxide, which happens to sublimate, or turn to gas, at a chilly -78.5 °C (-109.3°F). The fog you see is actually a mixture of cold carbon dioxide gas and cold, humid air, created as the dry ice “melts” oops, I mean sublimates.
Where is sublimation found?
Sublimation is an endothermic process that occurs at temperatures and pressures below a substance’s triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid.
How is sublimation useful?
Dye sublimation is also used to create digital watermarks on documents. This enables a forensic examiner to differentiate an authentic document from a forgery. Sublimation can be important in the recovery of compounds that are suspended or dissolved in a fluid or a solid like dry ice.
What is dry ice made of?
Dry Ice Production
Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO2. The liquid carbon dioxide is injected into either a block press or pelletizer.20 Apr 2009
