| Abstract: | Based on Bolzmann relation of the entropy of statistical physics and thermodynamic probability,the connection of the chemical potential energy between a certain component part and its pure component part in ideal solution was obtained and the relationship of the chemical potential energy between a certain component part and its pure component part in practical solution was also explained by the method of probability statistics.The osmotic pressure of osnotic phenomenon in plant physiology was analysed by using the obtained mathematical model of chemical potential energy of a certain component part in practical solution.The direct ratio of osmotic pressure and solution concentration in thin solution to the temperature of thermodynamics(i.e Fantoph Law) is obtained. |
