It is well known that when gas is cooled at a constant pressure its volume decreases.
众所周知,当气体在定压下冷却时,它的体积减小。
We're not going to have the constant pressure heat capacity, but the constant volume heat capacity.
我们将不会具有恒定的压力热容量,而是具有恒定的体积热容量。
It relates the pressure, volume, and temperature together.
它把压强、体积、温度联系在一起。
The piston has a cross-sectional area, a, and the force pressure is force per volume area.
我们以活塞系统为例,来说明膨胀功。
You just change volume to pressure and basically you're looking at enthalpy under a constant -- anything that's done at a constant volume path with energy, there's the same thing happening under constant pressure path for enthalpy.
可以看到这就是把体积换成了压强,一般我们都是在一种恒定状态下,考虑焓的,任何在恒容条件下,能伴随能量变化的东西,也在恒压条件下伴随焓同样地变化,所以你可以经常。
As it does that it changes the volume of the heart and gives the - creates the pressure that moves blood around your body, so it has that muscular system.
这使心脏的体积发生变化,产生了足以使血液流遍全身的压力,这就是心脏中有肌肉系统的原因
