Yet, the temperature goes up. So, I can have a temperature change which is an adiabatic temperature change.
它与外界不会,有物质或者能量的流动,然而系统的温度升高了。
And then maybe I raise the temperature to whatever, room temperature, maybe 20 degrees hotter than room temperature. And I again say OK, now how much heat do I need to raise this thing's temperature by 1 degree?
我可能把温度升到,比如室温,或者比室温高20度之类,然后我再说,好,现在要把这个东西的温度,升高一度需要多少热量?
When they separate, the primers that you've added automatically bind through the process of hybridization, and then you turn up the temperature to the optimum for Taq polymerase and DNA synthesis starts.
当双链解旋后,加入的引物就会在杂交的步骤中自动,和解旋后的DNA结合,然后你再将温度升高至,Taq酶的最适温度,DNA就开始合成了
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。
All the energy that is inserted into this, which might be turbulence initially, becomes heat, or becomes -- it raises the temperature.
由振动引起的所有,进入系统的能量最后都变成了热,因此温度便升高了。
And so an experiment said the gas didn't increase its temperature when it expanded the vacuum.
这个实验告诉你,气体在向真空膨胀的过程,中温度没有升高。
The same temperature increase, work and heat, and we have a relationship between heat and work.
同样的温度升高,功和热,因此我们可以得到功和热的关系了。
PROFESSOR: It increases and the temperature.
随着温度升高,压强升高。
And that gives rise to the heating that you can actually measure.
我们可以看到,它造成的温度升高。
Raise the temperature, and now entropy plays a bigger role.
升高温度后,熵就开始起作用了。
That's going to be your heating up of the gas.
这样气体的温度将会升高。
You're changing the pressure, and the temperature is going up.
你改变了压力,导致温度升高,偏T偏p是正数,偏T偏p是正数。
