So this is, first of all, even just on an absolute scale, this is way, way larger than the wavelengths we're talking about for baseball.
首先,即使在一个绝对标度下,棒球的尺寸也,远远地大于它的波长。
And we can we can do this in principle except for one important detail, which is that enthalpy just like energy u isn't measured on an absolute scale but on a relative scale, right?
除了一个重要的细节,就像能量U一样,它不是,以绝对标度度量的,而是以相对标度度量的,对吧?
And the temperature scale that turns out to be well-defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.
比如理想气体温标,它有精确的定义,并能引出绝对零度的概念,今天我们就先来谈谈它。
And so now, instead of using these reference points for the Kelvin scale, we use the absolute zero, which isn't going to care what the pressure is.
就像理想气体温标,与气体的种类无关一样,具有普适性,在开尔文温标中。
So, this temperature, this absolute zero here, which is absolute zero on the Kelvin scale.
在负无穷处,现在把绝对零度定义为,开尔文温标中的0度。
