And why does water in particular have such a high specific heat capacity?

为什么水的比热容特别高？

But a temperature change also depends on something called the specific heat.

但温度变化也取决于 关于一个叫做热容量的东西。

Specific heat is a measure of how well a substance stores heat.

热容量是容量的量度 关于蓄热的文章。

Water, for example, has a very high specific heat compared to, say, aluminum.

例如，水具有非常大的热容量 比较一下，比如说铝。

Therefore, we can use the specific heat capacity of water.

因此，我们可以利用水的比热容。

In fact, the specific heat capacity of water is about five times that of common rocks.

事实上，水的比热容大约是普通岩石的五倍。

And how do we know the specific heat capacity?

我们如何知道比热容？

Okay, so specific heat capacity times mass times the change in temperature.

好的，比热容乘以质量乘以温度变化。

But a temperature change also depends on something called the specific heat. Specific heat is a measure of how well a substance stores heat.

但是温度变化也取决于一种叫做比热的东西。比热是衡量物质储存热量的能力。

Latent heat is the heat required to change the phase of a substance, and like specific heat, its value depends on the substance.

潜热是改变所需的热量 物质的相，如热容量，变化。

It says that the change in heat equals the specific heat capacity of the substance times its total mass times the change in temperature.

它表示热量的变化等于物质的比热容乘以其总质量再乘以温度变化。

Well, the greatest factor is probably that we used the specific heat capacity of pure water instead of the salt water that we actually created.

嗯，最大的因素可能是我们使用了纯水的比热容， 而不是我们实际创造的盐水。

Every substance has its own specific heat, and the higher it is, the more energy transfer -- in the form of heat -- it takes to change its temperature.

每种物质都有自己的比热，比热越高，改变其温度所需的能量转移（以热的形式）就越多。

Water, for example, has a very high specific heat compared to, say, aluminum. That means it takes much more heat to change the temperature of water compared to aluminum.

例如，与铝相比，水具有非常高的比热。这意味着与铝相比，改变水的温度需要更多的热量。

Well, I am happy to report that some noble chemists have worked hard to determine the specific heat capacities of hundreds of substances so that we don't have to.

好吧，我很高兴地向大家报告，一些杰出的化学家已经努力确定了数百种物质的比热容，因此我们不必这样做。

In general, the amount of heat transferred to or from a substance is equal to the mass x the specific heat (which we designate with a small c) x the change in temperature.

通常，传递给物质或从物质传递的热量等于质量 x 比热（我们用小写的 c 表示）x 温度变化。

Specific heat capacity, represented by a lowercase " s" , is the amount of heat required tp raise the temperature of one mass unit, like a gram or kilogram, of a substance by 1 degree Celsius.

比热容以小写字母“s” 表示，是将一个质量单位（如克或千克）的物质温度升高 1 摄氏度所需的热量。
