由于温度升高,气体膨胀了.

In consequence of its rise in temperature the gas expands.

气体膨胀一定对外做功吗?。

Must the gas expanding do work?

提出了冲击该、气体膨胀压和反射拉伸波在破岩过程中各自所起的不同作用。

The different effects of shock wave, gas expansion pressure, reflected extension wave are put forward.

在x射线图显示的是由爆炸产生的高温气体膨胀扩展.

The X - ray image shows an expanding shell of hot gas produced by the explosion.

气体和液体一样没有形状，但又不同于液体，气体膨胀时会充满任何盛放它的容器。

Like a liquid a gas has no shape，but unlike a liquid it will expand and fill any container it is put in.

根据上述，我们可能得出一个结论：气体膨胀时能作功…

From what is mentioned above can arrive at the conclusion that gas can do work while expanding.
