From particles to universe
molecular
definition
The smallest particle that can maintain the chemical properties of a substance unchanged
Features
Matter is composed of a large number of molecules
There are gaps between molecules
There is a force of attraction between molecules
There is repulsion between molecules
There are interactions between molecules
molecular kinetic theory
diffusion
When different substances come into contact with each other, they will enter each other.
The movement of molecules in a substance is related to temperature. The higher the temperature, the more violent the irregular movement of molecules.
thermal motion
The random movement of large numbers of molecules
