Of course in the reversible case, you're always pushing against an external pressure, which is essentially equal to the internal pressure.
当然在可逆的情况下,外压力,总是,等于内部压力。
And he's seen me work under pressure.
而且他见过我如何在压力下工作。
Let's imagine maybe instead we just immediately dropped the pressure let the system expand against the lower pressure.
现在假设,我们很快地降低压力,让系统在低的外压力下膨胀。
They got lost in the fear or pressure performing at this high level.
在恐惧和压力下,因赛事之高,而迷失。
Because we did work at constant pressure, and so it's just volume difference times pressure.
因为是在恒压下做功,所以功就等于体积变化乘以压力。
And so, again, we see a temperature increase, and we know the work, and the temperature increase, it's a constant pressure thing.
好,我们看到温度升高了,然后我们有做功量和温度的升高量,这是一个恒定压力下的值。
