evaporation
C1Scientific/Technical, Formal, Neutral
Definition
Meaning
The process by which a liquid turns into a vapour (gas), typically due to heating.
The gradual disappearance or diminution of something; the act of making something volatile or insubstantial.
Linguistics
Semantic Notes
In scientific contexts, 'evaporation' specifically refers to the surface phenomenon of a liquid changing to vapour at temperatures below its boiling point. In figurative use, it implies a slow, passive, and often complete disappearance.

Usage
Context Usage
Business
Refers to the loss of capital, market value, or profits. 'The sudden market crash led to the evaporation of billions in shareholder value.'
Academic
Central term in physics, chemistry, hydrology, and climate science. 'The study measured soil moisture loss via evaporation.'
Everyday
Used for liquids drying or things disappearing. 'The puddles are gone after the sun caused their evaporation.'
Technical
Precise physical process, often quantified. 'The cooling effect is achieved through adiabatic evaporation.'
Examples
By Part of Speech
verb
British English

Learning
Memory Aids
Mnemonic
Imagine a VAPOUR RATION - the 'vapour' is created, and the liquid's 'ration' decreases as it evaporates.
Conceptual Metaphor
DISAPPEARANCE IS EVAPORATION (e.g., 'His confidence evaporated'). CHANGE OF STATE IS A JOURNEY (liquid 'escapes' as gas).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque from 'испарение' for figurative uses where 'disappearance', 'vanishing', or 'dissipation' is more natural. 'Evaporation' in English can sound slightly technical even in metaphors.
Common Mistakes
- Using 'evaporation' for boiling (which is 'vaporization' or 'boiling'). Confusing 'evaporation' (surface process) with 'distillation' (separation process). Using it as a countable noun (*'an evaporation').

FAQ
Frequently Asked Questions
No. Evaporation occurs at any temperature from the surface of a liquid. Boiling is a rapid vaporization that occurs throughout the liquid at a specific temperature (boiling point).
Yes, figuratively. It often describes the sudden or gradual disappearance of abstract things like hope, money, or tension (e.g., 'The profits evaporated').
Heat (temperature) is the primary factor. Increased temperature provides more energy for liquid molecules to escape as vapour. Other factors include surface area, humidity, and air movement.
Evaporation is the physical process from surfaces (soil, water). Transpiration is the biological process where water evaporates from plant leaves. Together, they form 'evapotranspiration' in environmental science.
