Because the molar volume of solid for water is bigger than that for liquid.
固体水的摩尔体积,比液体水的摩尔体积大。
So it「s RT over molar volume minus b.
等于rt除以摩尔体积减去b的差。
That」s just the molar volume of the gas.
这是气体的摩尔体积。
The molar volume is being changed a little bit trying to make things collide with each other, they can't occupy the same volume.
摩尔体积发生了很小的改变,如果你试图使气体分子间相互碰撞,他们不能占据同一个位置。
So the first approximation is, you can realize that the molar volume of the gas is always much bigger than the volume of the solid or the liquid.
第一个近似是,你会发现气体的摩尔体积,远远大于固体,和液体的摩尔体积。
It is found that the parameter is directly proportional to the molar volume of liquid at the normal boiling point, and its values have the additivity of groups.
这个参数的值与正常沸点下液体的摩尔体积成正比,且具有基团加和性。
Is going to be given by the molar volume of a under these conditions in the pure liquid dp.
由给定条件下的液体的,摩尔体积乘以dp给出。
O what happens if the molar volume for the liquid is bigger than the molar volume of the solid.
会怎么样,如果水的摩尔体积,比固体的摩尔体积大?
And it was supposed that the influence of the pressure on the system is only effect upon the exess molar volume of the system rely on the relationship of Gibbs free enthalpy with the pressure.
