tepelné

Tepelná is a feminine singular form of the Czech adjective tepelný, meaning heat-related or thermal. It is used to describe nouns that pertain to heat, temperature, or heat transfer. The form follows grammatical agreement with the gender of the noun it modifies, and is part of a family of terms derived from teplo, meaning heat.

In linguistic and technical contexts, tepelná appears in many everyday and scientific phrases, such as tepelná energie (thermal energy), tepelná vodivost (thermal conductivity), tepelná kapacita (thermal capacity), tepelná izolace (thermal insulation) and tepelná bilance (thermal balance). It is also common in discussions of heat transfer phenomena and building physics, where it helps specify properties or processes related to heat flowing through materials or structures.

The term is widely used across disciplines including physics, engineering, materials science and construction. It does not denote a single concept but rather a descriptor that can modify a range of feminine, masculine or neuter nouns depending on the specific expression, for example tepelná ztráta (thermal loss) or tepelná rovnováha (thermal equilibrium).

Etymologically, tepelná derives from teplo (heat), with the typical Slavic adjective formation that yields tepelný (masculine), tepelná (feminine) and tepelné (neuter), along with corresponding plural forms. This pattern allows precise agreement with the noun in Czech phrases describing heat-related characteristics or processes.
