And it's always going to come down to calculating the appropriate free energy, and how it changes in the process.

这总是涉及到计算,适当的自由能，以及这些自由能在过程中如何变化。

Whereas under these conditions, these quantities, if you look at free energy change, for example at constant temperature and pressure, H you can still calculate H.

但是，在这些条件下，这些物理量，如果我们考察自由能的变化,例如在恒定的温度和压强下，我们仍然可以计算。

Even though the signs of the enthalpy changed, and the signs of the entropy changed because it's a combination of the two that matters.

即使自由焓的符号发生变化，熵的符号也会发生变化,因为这两部分都起作用。
