In thermodynamics, the volume of a system is an important extensive parameter for describing its thermodynamic state. The specific volume, an intensive property, is the system's volume per unit of mass. Volume is a function of state and is interdependent with other thermodynamic properties such as pressure and temperature. For example, volume is related to the pressure and temperature of an ideal gas by the ideal gas law. The physical volume of a system may or may not coincide with a control volume used to analyze the system.

  • 熱力學系統的體積是在描述熱力學狀態時,重要的外延性質。比容是對應的內含性質,是單位質量的體積。體積為一狀態函數,和其他熱力學性質(如壓力、溫度)之間有相互關係。例如理想氣體的體積就可以依理想氣體定律,用壓力及溫度來表示。 一系統的體積可能與分析系統所用的控制體積重合,但也可能不重合。 (zh)
