You need a functional form that connects the value at one state of matter, the freezing point of water to another phase change, the boiling point of water.
你需要一个函数形式来,连接物质某个态对应的温度值,如水的冰点,和另一个相变,如水的沸点。
OK, so, the thing about a state function is that the function has a value for initial conditions and at final conditions.
态函数的特点是,在初始状态有一个值,在末状态也有一个值。
It is the value of the radius of the ground state electron orbit in atomic hydrogen.
它就代表氢原子基态电子,的轨道半径。
We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.
我们上周五知道了,在讨论能量的时候,基态指,n等于1的态,它能量最低,是,最稳定的态。
So, after the second line for code here char * s1 gets the return value of get string this is what the state of our world looks like.
在第二行之后,这个代码char,*s1,等于GetSting的返回值,这就是它看起来的状态。
If I look at different points in my container during that path, I'm going to have to use a different value of pressure or different value of temperature That's not an equilibrium state, and that process turns out then to be an irreversible process.
如果我要研究在路径中容器里的,不同的点,我就得在容器里不同的点上使用,不同的压强值,或不同的温度值,实际上这不是个平衡态,这个过程是,不可逆过程。
