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，量热法公式给出了 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？

That means we can tell the  difference between two moonlit nights with only a small change in the amount of light, but it takes a bigger absolute change to tell the difference in two brightly lit rooms.

这意味着我们可以通过光量的微小变化来区分两个月夜之间的区别，但需要更大的绝对变化才能区分两个明亮的房间。
