气体分子与液体、固体分子存在着很大的不同,气体分子的微观模型可以描述为:气体分子可看做没有相互作用力的质点,气体分子间距大(约为分子直径的10倍),分子力小(可忽略)。正因为如此,气体才没有一定的形状。我们知道分子总是不停息地做热运动,当然气体分子也不例外,并且比液体、固 Gas molecules are very different from liquids and solid molecules. The microscopic model of gas molecules can be described as follows: gas molecules can be seen as particles without interaction forces, with large gas molecules (about 10 times the molecular diameter), molecules Small force (negligible). Because of this, gas does not have a certain shape. We know that molecules do non-stop heat movement, of course, gas molecules are no exception, and more than liquid
