Reviewed by Psychology Today Staff. Sublimation is a defense mechanism that involves channeling unwanted or unacceptable urges into an admissible or productive outlet.
What is sublimation by Sigmund Freud?
The concept of sublimation has a central role in Sigmund Freud’s psychoanalytic theory. Sublimation is a defense mechanism—an unconscious psychological defense that reduces the anxiety that may result from unacceptable urges or harmful stimuli. 1
What is sublimation with 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 are 5 examples of sublimation?
7 Sublimation Examples in Daily Life

What is the meaning of sublimation in psychology? – Related Questions
What does sublimation mean in philosophy?
Sublimation is a psychoanalytic concept invented by Sigmund Freud to describe the transformation of tendencies or instincts in lower rates and higher sentiments. For example, the artist transforms his sexual impulses through its aesthetic achievements.
Who invented sublimation in psychology?
First developed by Sigmund Freud, the psychoanalytic theory behind sublimation (and defense mechanisms) sees personality as primarily comprising three components: id, ego, and super ego.
What is the principle of sublimation technique?
Sublimation is used for the separation of a solid-solid mixture where one of the components sublimes (converts from solid state to gaseous state without forming liquid) upon heating, leaving behind the other components that are non-sublimable.
Why sublimation method is used?
Sublimation is a technique used by chemists to purify compounds. A solid is typically placed in a sublimation apparatus and heated under vacuum. Under this reduced pressure, the solid volatilizes and condenses as a purified compound on a cooled surface (cold finger), leaving a non-volatile residue of impurities behind.
What is the importance of sublimation?
Sublimation can be important in the recovery of compounds that are suspended or dissolved in a fluid or a solid like dry ice. The compounds can be recovered, at least in crude form, by allowing the suspending matrix to sublimate away.
What is the process of sublimation step by step?
A Step by Step Guide to Sublimation Printing on Products
- Create an artwork/design on a product using a product design software.
- Send the design to a sublimation printer and reproduce it onto a transfer paper.
- Use heat press and print the graphic onto the product.
What happens during sublimation?
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.
Where does sublimation happen?
The process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO2) is an example of a solid that undergoes sublimation.
Which statement is true about sublimation?
The correct answer is option 2, i.e. Sublimation is a process in which solid changes into the gaseous state without passing through the liquid state.
What is an example of sublimation in real life?
The best example of sublimation is dry ice which is a frozen form of carbon dioxide. When dry ice gets exposed to air, dry ice directly changes its phase from solid-state to gaseous state which is visible as fog.
Which statement is best describing the sublimation process?
Option B is the correct answer.
Sublimation refers to the state change directly from solid to gas.
Is sublimation positive or negative?
Answer and Explanation: As the heat energy is required in sublimation, so the enthalpy of sublimation is always positive. The entropy of gas is greater than the entropy of solid. Hence, the entropy in sublimation process increases Hence, the entropy change for sublimation is also positive.
What factors affect sublimation?
The factors of sublimation are:
- Temperature: Rate of evaporation increase with increase in temperature.
- Surface Area: The rate of evaporation increases on increasing the.
- Humidity: Humidity is the amount of water vapour present in air.
- Wind speed: The rate of evaporation also increases with increase in speed of the wind.
Does sublimation require heat?
Introduction. Sublimation is the process of changing a solid into a gas without passing through the liquid phase. To sublime a substance, a certain energy must be transferred to the substance via heat (q) or work (w).
What is the difference between sublimation and sublimation?
The key difference between sublime and sublimate is that the sublime refers to the verb describing the sublimation process whereas the sublimate refers to a noun that describes the end product of sublimation.
What is the opposite of sublimation?
The opposite of sublimation is vapour deposition. The term “sublimation” only applies to a physical change of state and not to the transformation of a solid into a gas during a chemical reaction. One common example of sublimation is solid carbon dioxide, known as dry ice.
