So at this point the temperature will change.
在这点温度会改变。
And that will end up winning out at basically any realistic temperature where the stuff really is a gas.
在体系仍然处于气体状态的温度下,熵战胜了能量。
If I then put it back into its original condition, lower the heat say, temperature back to body temperature and reduce the pH down to seven again, the molecules will re-nature.
假如我把烧杯的温度恢复到初始状态,降低温度,温度降低到体温,将pH值降低到七,这些分子会复性
Now, if I want to change those quantities; change the temperature, change the volume, how will it change?
如果我现在打算改变这些量;,改变温度,改变体积,它会如何改变?
And so for many, many problems, especially on exams, especially on this first exam, you will be able to say that this is the relationship between internal energy and temperature.
对于很多问题,特别是考试中的问题,你们要能够说出来,这是内能与温度的关系。
In other words, the order of taking the derivatives with respect to pressure and temperature doesn't matter And what this will show is that dS/dp dS/dp at constant temperature, here we saw how entropy varies with volume, this is going to show us how it varies with pressure.
换句话说,对温度和压强的求导顺序无关紧要,结果会表明,恒定温度下的,对应我们上面看到的,熵如何随着体积变化,这个式子告诉我们,熵如何随着压强变化。
