The result is what chemists called a 'violently exothermic reaction', in this case known as a fluorine fire.

产生的结果被化学家称为“剧烈的放反”，也就是氟火。

It gets warm because of an exothermic chemical reaction.

由于放化学反， 变暖。

And by the same token, exothermic reactions, which release heat fair better at low temperatures.

出于同样的原， 放反在低温下以更好地释放。

And since exothermic reactions produce heat, that heat tends to favor the reverse endothermic reactions.

由于放反产生， 此往往有利于反向吸反。

We tend to think of endothermic and exothermic animals as two sides of a coin, as if you're one or the other.

我们喜欢把内温性和外温性看成硬币的两面，似乎你必须是两者之一。

In addition to the exothermic hand-warmers that we have out there, there are also endothermic chemical ice packs for treating injuries.

除了我们现有的发暖手器外，还有用于治疗损伤的吸化学冰袋。

And it’s an exothermic reaction, meaning it releases energy in the form of light and heat, the flames you see and feel, and some other byproducts.

这是一种放反，意味着以光和的形式释放能， 你看到和感觉到的火焰， 以及其他一些副产品。
