Because, when you ask yourself that question, you should consider what is the thermal energy versus the bonding energy?

这是因为，对于这个问题，我们应当考虑到,什么样的热能,对应于键能？

If the bonding energy is very strongly negative, thermal energy isn't great enough to disrupt those bonds and allow those bonds to be broken and then have fluidity.

如果键能非常强，热能并不足以,打破这些化学键,破坏这些化学键,并使它们液化。
