Hello.
00:01
Today we'll be talking about chapter 11, question six, which asks us to consider states and phases.
00:10
So a state is just the qualification or the classification of matter as either a solid, liquid, or gas.
00:29
There are a few other states of matter, such as plasma, supercritical fluid, but in general, these are the most common classifications.
00:37
And state is just that classification.
00:41
Phases are not very different.
00:47
Phases of matter are a little bit more specific to an individual chemical compound.
00:53
Liquid and gas phases don't really have any difference between states and phases.
01:02
However, it turns out we can have multiple kinds of solids.
01:06
So this is compound dependent.
01:14
For example, if we draw carbon, graphite, we would say that this is carbon in the solid state, and this is also the graphite phase of carbon...
