家用暖气以电流的形式吸收能量,然后以热量的形式将其释放出去。
A household radiator absorbs energy in the form of electric current and releases it in the form of heat.
能量通过点火柴燃烧释放出来。
The energy is released by combustion on the application of a match.
相反的带电粒子聚集在一起,抵消了电的张力,释放出大量的能量,就是我们看到的闪电。
The coming together of the oppositely charged particles neutralizes the electrical tension and releases a tremendous amount of energy, which we see as lightning.
So if we have a negative change in energy for any reaction as it's written, what that actually means is we're giving off energy as the reaction proceeds.
如果我们像这里写的这样,在任何一个反应过后,得,到的能量变化为负值,这就意味着我们在这个过程中放出了能量。
So, if we have energy that's released, would you say that the chlorine ion is more or less stable than the chlorine atom?
那么,如果我们放出了能量,你认为氯离子比氯原子,更稳定还是更不稳定呢?
this happens spontaneously, you actually get energy out of the reaction as this happens.
这是自发的,当反应发生的时候,你会自发地放出能量。
