The S & P Five Hundred index gained over twenty percent its largest increase in six years.

Remember, we didn't hybridize the 2 p y orbital, so that's what we have left over to form these pi bonds.

记住，我们并没有杂化2py轨道，这是我们剩下的那个行成了π键。

Minus p, right? But in fact, if you go back to the van der Waal's equation of state b here's RT over v minus b.

再减去p，对吗，但是实际上，如果你代回范德瓦尔斯气体的状态方程,这里是RT除以摩尔体积减去。

du/dV So now our du/dV, dp/dT at constant T is just T times dp/dT which is just p over T minus p, it's zero.

现在我们的恒定温度下的，等于T乘以dp/dT，在这里,等于p除以T，最后再减去p，结果是0。
