Question

Does the stability property of particles of a solution means the property of the particles of the solution to settle down under gravity?

Answer 1

We know that matter (anything with mass) attracts matter. This is a fundamental law of physics. The attraction of any mass to another mass is called gravity. (But it is a relatively weak force, and it doesn't work well on the atomic level.) How does it do this? We don't know how it does what it does. We only know that it does it.
