Astronomers have been able to take the temperature of planets around other stars, first with telescopes in space but more recently with ground-based instruments, as my collaborators and I have done.

天文学家已能够对其他恒星周围的行星测量温度，起初用的是太空望远镜但近来用的是地面仪器设备，就像我的合作者与我所做的那样。

If temperatures overnight are already very close to the freezing point, then this drop of just a few degrees can take the temperature below freezing.

如果夜间的温度已经非常接近冰点，那么仅仅下降几度就可以使温度降到冰点以下。

Take the person's temperature, if it is 40℃ or higher, take the person to hospital as soon as possible!

测量病人的体温，如果是40℃ 或更高，尽快送病人去医院！

And then we can take the derivative with respect to temperature, it's just R over molar volume minus b.

这样我们求,压强对温度的偏导数，结果等于R除以摩尔体积V杠减去b的差。

It's just how much heat is involved when we change the temperature. Now, the products have some heat capacity associated with them right, it takes a certain amount of heat if we make their temperature change, to either put it in or take it away, depending on which direction the temperature is changing.

问题就是当我们改变温度时,有多少热量发生了转移,生成物具有一定的热容,如果我们改变,它们的温度，就要输入或,提取一定的热量,这取决于温度改变的方向。

You take your room temperature liquid helium and you cool it with liquid nitrogen to 77 degrees Kelvin, the new, you're not quite there yet 77k unfortunately right? Then you take hydrogen you cool it would liquid nitrogen to 77, then you can use your hydrogen gas.

首先要有常温的氦气,拿液氮把它冷却到77k，那个新来的7,你不坐在那儿，对吧？,然后用液氮把氢气降温到,然后就可以使用这个氢气了，想要用氢气来做焦耳-汤姆孙实验。
