cieplnych

Cieplnych is a Polish adjectival form related to heat and temperature. It is used in technical and scientific language to describe objects, processes, and properties connected with heat energy. The base form is cieplny, and like other adjectives it changes according to gender, number, and case. The neuter singular nominative form is cieplne, as in źródło cieplne (a heat source), while the plural forms may appear as cieplne in some contexts, and cieplnych in others where the noun is in genitive plural, for example źródeł cieplnych (of heat sources) or różnice cieplnych (thermal differences).

In practice, cieplnych most often functions as the genitive plural or other plural forms of the adjectivecieplny, and it appears in phrases describing multiple heat-related elements when the governing noun is in a case that requires this ending. The adjective is commonly found in technical terms and specifications in fields such as thermodynamics, heating, ventilation and air conditioning (HVAC), and energy engineering.

Relation to other terms: In everyday Polish, termiczny is the more common synonym for thermal or heat-related. Cieplny and its inflected forms are typical in specialized or older texts and in engineering jargon. Understanding the different endings helps in properly constructing phrases like instalacje cieplne (thermal installations), różnice cieplne (thermal differences), and źródła cieplnych (of heat sources) when needed.
