They're actively engaged in the material, actually seeing the phenomena, by making measurements of real world experiments.

学生们能自主地参与到物质中，看见真切的现象，通过对真实世界实验,做出测量。

And again there, too, you saw an experimental result you were presented with that says, well at least to the extent that it could be measured, it was obviously getting very small.

再一次，你看到了一个,你经知道的实结果，至少在实验测量的范围内，对理想气体条件下的气体这一项很小。

When we do experiments, each group of three has an experimental setup to measure the phenomenon.

当我们做实验的时候，每个三人小组建立实验设备,来测量观察的现象。

Now of course, it was a psychological experiment, they had all these different measures, taken before/after.

这是个心理学实验，在实验前后进行各种测量。

Joule actually did this experiment, and he observed that for the gas expansions that he could do, that the temperature did not increase measurably.

事实上焦耳的确做了这个实验，他做到了,他能达到的最好实验要求，发现在可测量范围内没有观察到温度上升。

This one turns out to be the heat capacity, and this one turns out to be something that we measure in the Joule-free expansion.

其实，这就是热容，这是焦耳自由膨胀实验中,我们要测量的物理量。

This is real, unlike the Joule coefficient which is very small so that most gases have tiny Joule coefficients. So if you do a Joule experiment, you hardly measure a temperature change. With real gases, here you do actually measure it. You can feel it with your finger on your bicycle tire.

系数那样小以至于,大多数气体的焦耳系数,都很小，所以如果你做焦耳实验,很难测量出温度的变化,对于真实气体，你可以测量它，你能通过手指按在,自行车轮胎上来感觉到它。

For example, one of the experiments we do is measure the magnetic field of current coil, and after we do the experiment, we all have a passive visualization that shows the same experimental set-up, except we add to that.

比如，我们做的一个实验就是,测量电线圈的磁场，在我们做完实验之后，我们都感受到了一个直观化的过程,它展现了同样的实验过程，只是那是我们加的。

So we need an experiment that will enable us to measure this quantity.

因此需要设计实验,来测量它。

It's tabulated in books, and this we can measure p in the experiment. Delta p here is the change in pressure from the left side to the right side, and we can put a thermometer, measure the temperature before the experiment and measure the temperature after the experiment.

这列在书上，这个量我们在,实验中也可以测量，在这里Δ,是从左边到右边的压强变化，我们可以放一个温度计，去测量实验前的温度,再去测量试验后的温度。
