isentrope
C2+Exclusively technical/scientific
Definition
Meaning
A line on a graph or diagram connecting points of equal entropy.
In thermodynamics and statistical mechanics, a curve or surface representing states of a system with constant entropy. In meteorology, it can refer to a line of equal potential temperature, representing adiabatic processes.
Linguistics
Semantic Notes
The term is domain-specific to thermodynamics, fluid dynamics, and atmospheric science. It denotes a specific type of isoline, similar to an isotherm or isobar, but for entropy.

Examples
By Part of Speech
adverb
British English
- The air expands nearly isentropically.
American English
- The flow was treated isentropically.
adjective
British English
- The process was assumed to be isentropic.
American English
- We modeled an isentropic compression.
Examples
By CEFR Level
- On the thermodynamic diagram, the air parcel ascends along an isentrope.
- Engineers design turbine blades to operate as close to an isentropic process as possible.
Learning
Memory Aids
Mnemonic
Think: ISO (same) + ENTROPY. An ISENTROPE is a line where entropy is the SAME.
Conceptual Metaphor
A PATH of constant disorder. A ROAD where the 'messiness' (entropy) doesn't change.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изотропный' (isotropic). 'Isentrope' is 'изэнтропа' or 'адиабата' in specific contexts.
Common Mistakes
- Mispronouncing as 'eye-SEN-trope'. Correct is 'EYE-sen-trope'.
- Confusing with 'isotherm' (constant temperature) or 'isobar' (constant pressure).

Frequently Asked Questions
In the context of a reversible adiabatic process, yes, they are synonymous. An adiabat is a process path with no heat exchange, and if it is also reversible, entropy is constant, making it an isentrope.
Almost exclusively in advanced textbooks, research papers, or technical manuals related to thermodynamics, aerospace engineering, meteorology, or atmospheric physics.
No, the adjectival form is 'isentropic'. You would refer to an 'isentropic process' or 'isentropic surface', not an 'isentrope process'.
An isotherm connects points of equal temperature. An isentrope connects points of equal entropy. For an ideal gas undergoing an isentropic process, temperature can change.
