The purpose of immediate treatment is to cool the victim as quickly as possible to stop the body temperature from increasing.

I want to cool a gas with a Joule-Thomson experiment, what temperature do I have to be at?

给气体降温时,需要到达什么温度？

Now to make that happen, it's not adiabatic, right. If I wanted to do that, I'd need a heating element or something to cool, so I could make that temperature change happen, right.

要实现这点，它就不会是绝热的，对吧，如果我想做到这点,我需要一个加热元件或什么制冷的东西,这样我才能让温度变化。

The temperature is not going to cool as much for the irreversible process.

对不可逆过程,降温不会有可逆过程多。

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。
