One misconception is that fire is a plasma, the fourth state of matter in which atoms are stripped of their electrons.

一种误解是，火是一种等离子体，是原子失去电子的第四种物质状态。

So we take a gas, we put a huge amount of energy into it, and that turns it into the fourth state of matter, plasma.

所以我们拿一种气体，我们把大量的能量放进去，然后把它变成物质的第四种状态，等离子体。
