以至于浑身发热，如果你摸气筒的阀门，相当于近似测量了进入轮胎的气体的温度，它会很热，对吧。

But if you touch the valve going into your tire which basically measures the temperature of the air going into your tire, that is getting hot, right.

所以若果你给轮胎，打了很多的气，你会觉得你感觉，阀门那儿非常的烫，这种压缩，基本上是一个绝热的压缩。

So if you've got to pump that tire really a lot, then you're going to you're going to really feel a lot of heat there. The compression of the basically it's an adiabatic compression.
