Noun
/kɒnˈkeɪv məˈnɪskəs/
A concave meniscus refers to the curved surface of a liquid in a container that dips downwards in the center, typical when liquid is attracted to the container's walls more than to itself. This phenomenon is observed, for example, in water in a glass tube. The term is frequently used in scientific contexts, particularly in chemistry and physics. The frequency of use is higher in written contexts, especially in academic texts and articles, rather than in everyday conversation.
Translation: La menisque concave qui s'est formé au sommet du mercure dans le baromètre indiquait la pression atmosphérique correcte.
When measuring liquids, it is crucial to observe the concave meniscus to ensure accurate readings.
Translation: Lors de la mesure des liquides, il est essentiel d'observer le menisque concave pour garantir des lectures précises.
The scientist demonstrated how the concave meniscus can be observed in various liquids under different conditions.
While "concave meniscus" is not a standard part of any idiomatic expressions, the concept of a meniscus is often involved in discussions about liquid levels and tension, which can have metaphorical uses.
Translation: Le menisque du liquide indique qu'il y a plus dans cet experiment que ce qui est visible.
Like a meniscus, the tension in the room dipped dramatically when the news broke.
Translation: Comme un menisque, la tension dans la pièce a chuté considérablement lorsque la nouvelle a éclaté.
The surface tension of the water created a meniscus that fascinated the students watching.
Translation: La tension superficielle de l'eau a créé un menisque qui a fasciné les étudiants qui regardaient.
His attention to detail was like the perfect meniscus, reflecting a clear understanding of the task at hand.
The word "meniscus" comes from the Greek word "meniniskos," which means "crescent," and it relates to the crescent or curved shape of its surface. The prefix "concave" derives from the Latin word "concavus," meaning "hollow" or "sunk."
Synonyms: - Curved surface - Dip
Antonyms: - Convex meniscus (the opposite curvature, where the surface bulges outward) - Flat surface
In summary, the term "concave meniscus" is crucial in scientific contexts, particularly when discussing liquids in containers. It has specific meanings related to physical characteristics and has implications across different disciplines, although it does not typically feature in idiomatic expressions.
