Sublimation is the act of turning an molecule from its gaseous state directly to its solid state. A commonly used example is the sublimation of carbon dioxide gas (CO2) into 'dry ice'. In the sublimation process, desiccation, or the removal of water, also occurs. (Hence the nickname 'dry' in dry ice) Although food products are not made from the process of sublimation, foods can be shipped with sublimed products (e.g. dry ice) in order to allow longer periods between packaging foods and cooking them.

∙ 10y agoOne usage of sublimation is the example of sublimation of dry ice. When dry ice sublimes, it uses up energy from the surrounding, hence it has a cooling effect on the surroundings without leaving any residue behind.

Is there a discoverer of sublimation?
Nobody really knows who discovered sublimation. Gerber, the founder of Chemistry, however was the person that first explained it. It is said to be thought that the first person to ever break open a geode was the first person to discover sublimation.
Sublimation process of sodium chloride and camphor?
sublimation of camphor
How do you separate naphthalene from sand?
by sublimation
What is the change from a solid directly to a gas is called?
When a solid turns directly into a gas without becoming a liquid it is called sublimation. The reverse of this process is called deposition.
What is the process of dry ice being exposed to the air and changing into a vapor?
"sublimation"
Is there a discoverer of sublimation?

What are the applications of sublimation in chemistry?
Sublimation is the primary process by which dry ice turns into carbon dioxide. This process uses energy from the atmosphere which causes a cooling effect. Many people use dry ice to keep things cold, such as during hunting or fishing trips.
What two apparatus are used in the sublimation separation process?
Chemists use a special sublimation apparatus.See this link for an image.
What is a sentence using sublimation?
In chemistry, sublimation refers to the process in which a solid substance converts directly into a gas without passing through the liquid state.
What process you would use to separate camphor crystals and sand?
Sublimation
Is sublimation an element or an atom?
Neither. Sublimation is a process.
What is the process of sublimtion?
The process in which a solid directly changes into vapours without getting into liquid phase is termed sublimation and such solids are termed sublime solids. Example: nephthalene, solid carbondioxide, iodine, etc.
What is the process called when ice turns into water vapor?
I think the answer is sublimation
Where is a sublimation?
Sublimation is the process when solid is turns to gas directly
Sublimation process of sodium chloride and camphor?
sublimation of camphor
What is the process called when a solid turns into a gas?
sublimation
How do you separate naphthalene from sand?
