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“剧烈的放热应”，也就是氟火。

It gets warm because of an exothermic chemical reaction.

放热化学应， 它会变暖。

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

出同样的原因， 放热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.

放热应会产生热量， 因此热量往往有向吸热应。

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.

除了我们现有的发热暖手器外，还有用治疗损伤的吸热化学冰袋。

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.

这是一种放热应，意味着它以光和热的形式释放能量， 你看到和感觉到的火焰， 以及其他一些副产品。
