Firstly, he said the experiments had been done on dry - or briefly soaked - rocks at room temperature and pressure.

他说首先，这些实验是在处于室温和室内压力的干燥的或是经过简单浸泡的岩石上作的。

But we've defined the enthalpy of those elements in their stable state at room temperature and pressure as zero, right?

但我们已经定义了这些，元素处于它们室温和常压下，最稳定的状态时的焓为零，对吧？

Water (H2O) is a hydrogen and oxygen are two elements of inorganic, at room temperature and pressure is a colorless odorless transparent liquid.

水(H2O)是由氢、氧两种元素构成的无机物，在常温常压下为无色无味的透明液体。

And I didn't specify the conditions, but if we were to do this under ordinary chemical conditions of some, you'd say room temperature and pressure, right, they all happen spontaneously.

我并没有特别说明反应条件，但是如果我们在通常的化学条件下,实现这些化学反应，比如在室温和大气压下下，他们都是自发的。
