| Abstract: | Using the carnahan starling equations of state which contains modified properties of inner pressure, some analytical expresions are derived in hard sphere liquids, including isothermal compressibility, isobaric expansibility, heat capacity and ultrasound velocity. The values of the expresions are calculated in 9 kinds of typical hard sphere liquids, especially that of the ultrasound velocity. The results are found to be in agreement with those of the experiments. |
