kvapalné
Kvapalné is a term used in some contexts, particularly in older or specialized Czech scientific literature, to refer to a liquid state of matter. It is the Czech word for "liquid." While the modern and universally accepted scientific term for the liquid state is "kvapalina," the older form "kvapalné" might still be encountered. In physics and chemistry, a liquid is one of the fundamental states of matter, characterized by its ability to flow and take on the shape of its container while maintaining a relatively constant volume. Unlike solids, the particles in a liquid are not held in fixed positions but can move past one another. Unlike gases, the particles in a liquid are still close enough for intermolecular forces to hold them together. The transition between solid, liquid, and gaseous states is typically governed by changes in temperature and pressure. The term "kvapalné" therefore describes this particular phase, emphasizing its fluid nature.
