And we measure enthalpy with a weird little science called calorimetry.

我们用一种叫做法的奇怪小科学来测焓。

And finally, you learned some potential sources of error related to calorimetry.

最后，您了解了法关的一些潜在误差源。

In this study, researchers pit five different fitness watches against a metabolic calorimetry chamber, and measured estimated physical activity calorie expenditure.

在这项研究中，研究人员将五种不同的健身手表代谢室进行对比，并测了估算的体力活动卡路里支出。

Calorimetry is the science of measuring the change in heat associated with a chemical reaction.

法是测化学关的变化的科学。

Scientists have actually done on the calorimetry footwork for us, so we can actually predict how much heat a chemical reaction will produce.

科学家们实际上已经为我们完成了法步法，因此我们实际上可以预测化学会产生多少。

So there you go, the calorimetry formula gave an absolute enthalpy change of 6.2 kJ, while Hess's Law gives a change of 5.67 kJ. So, why the difference?

所以你走了，法公式给出了 6. 2 kJ 的绝对焓变， 而赫斯定律给出了 5. 67 kJ 的变化。 那么，为什么不同？

Any way that we can figure out the change of heat between the products and the reactants will work just as well, and that's where calorimetry comes in.

我们可以计算出产物和物之间的变化的任何方法都同样有效，这就是法的用武之地。

When doing calorimetry, we calculate a change in heat by measuring a change in temperature, but as we've said a billion times before, heat and temperature are not the same thing.

在进行法时，我们通过测温度的变化来计算的变化， 但正如我们之前所说的十亿次， 和温度不是一回事。
