A volcanic vent is a place on the Earth's surface where lava or gas can escape.

火山喷口是地球表面熔岩或气的地方。

Cooling systems use gases called refrigerants. Such gases can affect the atmosphere if they escape.

冷却系统使用一种叫制冷剂的气。如果这些气，可能会影大气。

Spectrometers can analyze gases escaping magma.

光谱仪可以分析岩浆的气。

If the rocks are volcanic, they could be tiny vessels left over from gases that escaped, called vesicles.

如果岩石是火山岩，它们可能是的气下来的微小容器，称为囊泡。

And when you tilt your glass while you pour your beer, you’re stopping most of the remaining gas from escaping.

如果您在倒啤酒时倾斜玻璃杯，就可以阻止大部分剩余气。

Same as when you're boiling a pot of water, when it goes from cold to hot and it bubbles, you start to see the gases come off.

和煮一壶水一样，从冷到热，它们会冒气泡，你可以看到气。
