網頁The liquid state sometimes is described simply as the state that occurs between the solid and gaseous states, and for simple molecules this distinction is unambiguous. However, clear distinction between the liquid, gaseous, and solid states holds only for those substances whose molecules are composed of a small number of atoms. 網頁2016年4月4日 · I start with the simplest possible formula: 1 mol of liquid has volume zero (or: negligible volume) 1 mol of ideal gas at standard T and p has volume 22.4 dm 3 Example: liquid water 18 grams, 18 *10 -6 m 3 water vapour 18 grams 22.4 *10 -3 m 3 The difference is equal to the water vapour volume to a very good approximation, isn't it ?
