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

因此，我们可以利用水的比热容。

And how do we know the specific heat capacity?

我们如何知道比热容？

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

为什么水的比热容特别高？

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。

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。

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。

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。

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。
