9.1.- 热力学的基本原理和基本概念

热力学是物理学的一个分支，属于现象学的一个分支，它研究的是真实的、非模型的系统，遵循的是实验方法。因此，它们的定义是通过近似和测量变量的方式进行实验。

从宏观上看，热力学系统是通过变量来定义的。可以测量大量的热力学变量，但只需要一个数字就可以明确地确定系统，即状态函数。压力、体积、温度、熵和焓是一些最重要的状态变量。

随着热力学变量的修改，物质的聚集状态发生变化。聚合的基本状态有固态、液态和气态，对于每一种元素或化合物来说，都有一定的压力和温度条件来发生状态变化。

为了简化实际的热力学系统和发生的状态变化，引入了理想气体模型概念。它们是由理想气体方程定义的。以同样的方式我们近似于理想的不可压缩液体。

在一个有液体的封闭系统中，液体和其汽相之间存在着热力学平衡。平衡状态下系统的压力和温度的演变定义了蒸汽压力的曲线，现有状态称为饱和状态。从这个演变过程中，温度-压力图表示。

这些概念的研究在实践中具有非常重要的意义，从根本上应用于水。例如，对理想的湿度、物质的收缩和膨胀的规范，然后应用于真实的热机，如涡轮机、喷嘴或蒸汽机，以评估运行制度。
