Sublimation is the transition of a substance directly from the solid to the gas state , without passing through the liquid state. ... The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
What is sublimation one line answer?
Answer: Sublimation is a change of state in which a substance upon heating transforms from solid directly to vapour/gaseous state without undergoing the liquid state . Few sublimable substances – iodine, naphthalene, camphor, anthracene, ammonium chloride etc.
What is sublimation class 9th?
The Changing of a solid directly into vapours on heating,and of vapours into solid on cooling is called as sublimation. The solid substance which undergoes sublimation is called sublime. The solid obtained by cooling the vapours of the solid called a sublimate. For Ex:camphor,Iodine,Ammonium Chloride,Naphthalene etc.
What does sublimation mean?
To sublimate is to change the form, but not the essence. Physically speaking, it means to transform solid to vapor ; psychologically, it means changing the outlet, or means, of expression from something base and inappropriate to something more positive or acceptable.
What are 3 examples of sublimation?
- “Dry ice” or solid carbon dioxide sublimes.
- Snow and ice can sublime in the winter months without melting.
- Moth balls sublime.
- Frozen foods will sublime and you will find ice crystals inside of the box or bag.
What is sublimation give an example?
Sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature . The phenomenon is the result of vapour pressure and temperature relationships.
What is sublimation with diagram?
SUBLIMATION – The process in which a solid directly changes into gaseous state without achieving the liquid state is called sublimation. In the diagram it is shown the sublimation of ammonium chloride.
What is the 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.
What is sublimation question and answer?
Solution: Sublimation is the process by which a substance changes from solid state directly to vapour state .
What's another word for sublimation?

What is sublimation in mental health?
Sublimation is one way that the ego reduces the anxiety that can be created by unacceptable urges or feelings . Sublimation works by channeling negative and unacceptable impulses into behaviors that are positive and socially acceptable.
What is sublimation Tshirt?
Sublimation shirt printing is a specific process of printing that first involves printing onto a special sheet of paper, then transferring that image onto another material (usually polyester or a polyester mix). The ink is then heated until it disintegrates into the fabric.
Which is capable of sublimation?
A number of solids are capable of sublimating at normal temperatures and pressures, including snow, iodine, arsenic, and solid carbon dioxide (dry ice) . Sometimes other materials can be made to sublimate by creating low pressure conditions.
Where is sublimation used?
Practical Applications of Sublimation
Sublimation of iodine may be used to reveal latent fingerprints on paper. Sublimation is used to purify compounds . It is especially useful for organic compounds. Because dry ice sublimates so readily, the compound is used to produce fog effects.
Is boiling water an example of sublimation?
Large bubbles of gas form throughout the the liquid and move to the surface, leaving the liquid. Steam is the gaseous water molecules that form above boiling water. ... Sublimation occurs when a solid changes into the gas state without passing through the liquid state.
How is sublimation used in everyday life?
As mentioned earlier, dry ice is one of the most popular examples of sublimation in real life . As the solid form of carbon dioxide, dry ice creates a smoky effect that is commonly used in ice cream parlors today. Because the substance is relatively safe to handle, it is often used for classroom demonstrations.
