f So we have now temperature in degrees Kelvin.
纵坐标是。
The lowest possible temperature in the Celsius scale is minus 273.15 degrees Celsius. So that begs the notion of re-referencing our reference point, of changing our reference points.
在摄氏温标中,绝对零度是-273。15摄氏度5,这样,我们需要重新定义参考点,将零度的参考点取在绝对零度处,而不是0摄氏度处。
And so redefining then the temperature scale to the Kelvin scale, where t in degrees Kelvin is equal to t in degree Celsius, plus 273.15.
以K为单位的温度,是以℃为单位的温度,加上273。15度。
Last time we reach the third law which is telling us that we can't quite get to zero degrees Kelvin .but that as the temperature approaches zero degrees Kelvin, the absolute entropy of a pure substance in perfect crystalline form is zero.
上次课我们得到了热力学第三定律,这个定律告诉我们我们无法,达到0K的温度,但是在我们接近绝对零度的过程中,以完美晶体形式存在的纯物质的绝对熵,也趋向于零。
