Soojusmahud

Soojusmahud is a term that appears in some Estonian-language discussions of thermodynamics to describe quantities related to the heat content of a system. It is not an officially defined quantity in standard thermodynamics, but rather a colloquial or pedagogical label used in certain educational texts and online discussions to unify or simplify references to heat-related properties.

Etymology: The word combines soojus, meaning heat, and mahud, meaning volumes or magnitudes, signaling its intended role as a quantitative measure of heat content.

Concept and usage: In practice, soojusmahud is used informally to group or compare quantities such as heat capacity (the amount of heat needed to raise temperature), enthalpy changes during processes, and sometimes internal energy changes. It may also refer to a composite view of heat-related properties in introductory explanations. The precise definition varies by author, and it does not replace established terms in formal thermodynamics.

Context: The term is more common in didactic materials or online discussions aiming to simplify the mental model of heat transfer rather than in technical standards. When encountered, readers should seek explicit definitions within the text to avoid ambiguity.
