It's constantly using internal energy to do mechanical work and enhance our hearing.

它一直在使用内部能量进行机械工作，并增强我们的听力。

So dealing with the whole internal energy equation thing would kind of be overkill.

因此， 处理整个内部能量方程的事情有点过分了。

– work and heat – as affecting a change in internal energy.

工作和热量 - 影响 内能的变化。

You're just increasing its internal energy.

你只是在增加他的内在能量。

That impact presumably relinquished all of that internal energy that the planet had when it first formed and has left it as a relatively dead and sluggish world.

据推测，那次撞击夺走了这颗行星最初形成时所拥有的所有内部能量，使它变成一个相对死寂和萧条的世界。

But the internal energy of the gas can change, so the system can do work, or have work done on it.

但是气体的内能可以改变， 所以系统可以执行工作，或者提交。

In fact, the change in the internal energy of the gas will be exactly equal to the negative of the work.

执行工作。事实上，能量的变化 内部气体等于功值的倒数。

So learning how to use your own internal energy is critical to being productive, and the best way to leverage your energy is by performing what I call Sprints.

因此，学习如何利用你自己的内在能量对于提高生产力至关重要，而利用你的能量的最好方法就是进行我所说的“冲刺”。

Another difference between isobaric and isothermal processes is that, since temperature is held constant in isothermal processes, the internal energy of the ideal gas can't change.

压力介电和介电工艺之间的另一个区别 热量是因为热量是恒定的。

This idea – that the change in internal energy is equal to the change in work plus the change in heat – is so fundamental that it's known as the first law of thermodynamics.

这个想法——内能的变化 等于工作变化加上工作变化。

Remember that measuring heat change is closely related to enthalpy, which we defined as the internal energy of a system plus the energy it uses to push the surroundings back and make room for its own pressure and volume.

请记住， 测量热变化与焓密切相关，我们将其定义为系统的内部能量加上它用来将周围环境推回并为自身压力和体积腾出空间的能量。
