Folyadékra

Folyadékra is a Hungarian grammatical form of the noun folyadék, formed with the suffix -ra/-re to indicate direction toward or onto a liquid. It is not a separate technical term, but a case form used in sentences to specify actions related to liquids. In both everyday and technical language it appears in phrases where something is directed at a liquid, such as adding reagents to a liquid or applying a substance to a liquid’s surface. The form is common in scientific, medical, and laboratory contexts.

Folyadék refers to a substance with a definite volume that flows and takes the shape of its container. It contrasts with a solid, which has a definite shape, and with a gas, which fills the available volume. Liquids are characterized by properties such as density, viscosity, and surface tension. They are studied in fields such as fluid dynamics and rheology; their flow behavior can be Newtonian or non-Newtonian, depending on how viscosity changes with stress.

In science and industry, liquids are central to processes like mixing, dissolution, extraction, and transport. The behavior of liquids under changes in pressure and temperature, and in contact with other phases, is governed by principles from hydraulics, buoyancy, and thermodynamics.

Note: As a grammatical form, folyadékra does not denote a substance by itself but marks direction toward a liquid within a sentence. See also: folyadék, folyadékfizika, folyadékdinamika, felületfizika.
