Now I assume we've all heard that like dissolves like, so the easiest way to figure out if a liquid is polar or non-polar is just to dump it in some water.

现在我想我们都听说过同类相溶，所以判断液体是极性还是非极性的最简单方法就是将其倒入水中。

You also learned how to notate a dipole moment or charge separation of a molecule, the actual physical mechanism behind " like dissolves like" , and why water is just so dang good at fostering life on this planet.

您还学习了如何记下分子的偶极矩或电荷分离、“同类相溶”背后的实际物理机制，以及为什么水在培育这个星球上的生命方面如此出色。
