And the path that I'm describing then, let's assume that we're raising the temperature up is this path right here.
经过一个,等压过程,路径就是这样。
so I'm heating up the system in this path here, and then to connect the 2 endpoints here, a constant temperature path.
需要再用,一个等温过程,这两个状态。
If I'm working under conditions of constant temperature and volume, that's very useful.
如果在恒定的温度和体积下,进行一个过程,这是非常方便的。
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。
