We call that a phase change, or a change of state.

称之为相变，或者状态的变化。

So that’s how heat affects phase changes. But what about how heat spreads?

这是热量如何影响相变。但是热量是如何传播的呢？

Like the snowball melting and vaporizing, each of these moments in the history of the Universe was like a phase change.

球的融化和蒸发一样，宇宙历史中的每一个瞬间都一个相变。

The value also depends on the phase change.

它的价值取决于材料。 该值也随相位变化而变化。

So that's how heat affects phase changes.

所以这是热的影响 相变。

As the phases change, inexorably, day after day, the angle of sunlight hitting the surface changes, bringing new things into our view.

随月相的变化，日复一日，阳光照射地面的角度也在变化，把新的事物带入的视野。

Gases, mixtures, surfaces, solids, phase changes, chemical reactions, electrochemical cells, sedimentation, and osmosis, to quote William H. Cropper.

引用 William H. Cropper 的话来说，包括气体、混合物、表面、固体、相变、化学反应、电化学电池、沉积和渗透。

We also talked about phase changes, including the critical point, the triple point, and how that all applies on Mars.

还谈到了形状变化，临界点 三相点，以及这如何适用于火星。

The power needed to effect the phase change could be fed to individual pixels by electrodes made of indium tin oxide, which is also transparent.

要激发相转变所需的能量可以由透明的铟锡氧化物电极向单个素提供。

So are we at another possible phase change here, where we kind of sleepwalk into a future that none of us actually wants?

那么， 是否处于另一个可能的阶段变化中，梦游到一个实际上都不想要的未来？

Instead, the amount of heat that gets transferred during a phase change is equal to the mass times what’s known as the latent heat.

相反，相变过程中传递的热量等于质量乘以所谓的潜热。

Instead, the amount of heat that gets transferred during a phase change is equal to the mass times what's known as the latent heat.

相反，它是相变期间传递的热量 质量等于所谓的潜热。

Today, you learned about thermal energy, as well as heat, and how much of it you need for both temperature changes and phase changes.

今天，您了解了热能和热能，以及温度变化和相变需要多少热能。

For example, this video on percolation showed a completely fascinating toy model for studying phase changes, a model where it's easier to make exact proofs.

例如， 这个关于渗透的视频展示了一个用于研究相变的完全令人迷的玩具模型，在该模型中更容易做出精确的证明。

You will undoubtedly have noticed how carefully Jordan observes the changing phases of the Magdalena River and how sympathetically he listens to the people whom he meets.

毫无疑问，您会注意到乔丹是多么仔细地观察马格达莱纳河的变化阶段，以及他是多么富有同情心地倾听他遇到的人。
