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

产生结果被化学家称为“剧烈放热反应”，也就是氟火。

It gets warm because of an exothermic chemical reaction.

于放热化学反应， 它会变暖。

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

出于同因， 放热反应在低温下以更好地释放热量。

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

于放热反应会产生热量， 因此热量往往有利于反向吸热反应。

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.

除了我们现有发热暖手器外，还有用于治疗损伤吸热化学冰袋。

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.

这是一种放热反应，意味着它以光和热形式释放能量， 你看到和感觉到火焰， 以及其他一些副产品。
