摘要
提出了关于气体的内能与焓的几点看法,指出内能与焓为温度的函数,而与压力、体积无关,并不是理想气体的特性。同时指出实际气体和非理想气体不是完全相同的概念,它们的区别在于实际气体的内能与焓不仅是温度的函数而且与压力、体积有关,而非理想气体的内能与焓则有可能仅是温度的函数而与压力、体积无关。
This article proposed some views on the internal energy and enthalpy of gases, and pointed out that are not properties unique to an ideal gas and that real gases and nonideal gases are not the same concept. The difference between the two conceptsis that the internal energy(U) and enthalpy(H) of real gases are not only a function of temperature but also a function of volume or pressure but that the U and H of nonideal gases possibly depend only on the temperature.
