condensation

 [kon″den-sa´shun]
1. the act of rendering or process of becoming more compact; compression.
2. the packing of dental filling material into a prepared tooth cavity.
3. a mental process in which one symbol stands for a number of components and contains all the emotions associated with them.
4. conversion from the gaseous state to the liquid or solid state; gas liquefaction.

con·den·sa·tion

(kon'den-sā'shŭn),
1. Making denser or more solid.
2. The change of a gas to a liquid, or of a liquid to a solid.
3. In psychoanalysis, an unconscious mental process in which one symbol stands for a number of others.
4. In dentistry, the process of packing a filling material into a cavity, using such force and direction that no voids result.
5. A chemical reaction in which two or more molecular entities combine, with the concomitant release of a molecule of water, ammonia, alcohol, or some other simple entity.

condensation

(kŏn′dĕn-sā′shən, -dən-)
n.
1. The act of condensing.
2. The state of being condensed.
3. An abridgment or shortening of something, especially of a written work or speech.
4. Physics
a. The process by which a gas or vapor changes to a liquid.
b. The liquid so formed.
5. Chemistry A chemical reaction in which water or another simple substance is released by the combination of two or more molecules.
6. Psychology The process by which a single symbol or word is associated with the emotional content of several, not necessarily related, ideas, feelings, memories, or impulses, especially as expressed in dreams.

con′den·sa′tion·al adj.

condensation

[kon′dənsā′shən]
Etymology: L, condensare, to make thick
1 a reduction to a denser form, such as from water vapor to a liquid.
2 (in psychology) a process, often present in dreams, in which two or more concepts are fused so that a single symbol represents the multiple components. In some cases of schizophrenia condensation, several thoughts and feelings fuse into a single verbal or nonverbal message and may be expressed in repetitive statements or gestures that can have a variety of meanings.

condensation (kän´densā´shən),

n a commonly used term for the insertion and compression or compaction of dental materials into a prepared cavity. Compaction is a more accurate term than condensation. See also compaction.

condensation

1. the act of rendering, or the process of becoming, more compact.
2. the process of passing from a gaseous to a liquid or solid phase. In animal housing this is a matter of great importance because of the need for a dry environment as a prevention against the spread of infection, especially those spread by inhalation.
