And subsequently germanium tetrachloride 88 was synthesized and measured to be 1.88.

随后，四氯化锗被合成出来了,密度测量出是1。

So in principle, if I measure how much hotter, I can determine how much heat was produced, and from that, I should be able H to calculate delta H at T1.

所以原则上，如果我测量，变热了多少，我就能确定，有多少热被产生,从中我就可以计算T1下的Δ

This is why people right tables and tables of H delta H's. Why you have delta H's from all these reactions, because this is basically the heat and the heat is something we can measure, we can control. We can figure out how much heat is going in and out of something.

这就是为什么人们一再提出ΔH的原因,为什么在所有的反应中你都能看到Δ,因为它就是热量，而且热量,是一种我们可以测量并且控制的东西，我们可以测量出有多少热量,从一些东西里面放出或被吸收。
