Back to the Basics

Before diving into this unit, it is really important to know the basic information on solids, liquids, and gases! It is, after all, what this whole unit is based off of.

Here are the basics:

Gas:
Spread out
Particles move very quickly/sporadically
No definite shape

Liquids:
More compacted than gas
Particles move slower, vibrating
Takes shape of container

Solids:
Particles very close together
Little to no movement
Has definite shape


You should also note that on phase change diagrams, the order goes solid, liquid, and then gas from left to right as it is traditionally ordered.
