分子吸引力

The law of universal gravitation states that every particle of matter in the universe attracts every other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

万有引力定律说明了宇宙中的物质的分子相互吸引，这种吸引力与它们的质量成正比，与它们的距离成反比。2 请将下面的句子翻译成中文。

Dipolar charges are a type of intermolecular force that has attraction between polar molecules.

偶极电引力是一种极性分子间的吸引力。

The outermost layer of Earth's atmosphere, lying above the thermosphere and extending thousands of kilometers into space, from which molecules having sufficient velocity can escape Earth's gravitation.
