- [Instructor] What we have depicted here

And we're using what's known as a particulate model.

And these are two dimensional particulate models

And so you can imagine each of these circles to,

or ions or atoms are interacting with each other.

Which determine what state of matter we are in.

which of these quadrants represent matter

which represent matter in a liquid state,

and which represents matter in a gas state.

All right, so there's a few that might have been

If you imagine each of these circles to be an ion,

you could imagine these to be ionic solids

to be atoms that are forming covalent bonds

If you imagine each of these circles are molecules,

then you could imagine this is a molecular solid.

You could also imagine that each of these

And so we're dealing with a metallic solid.

But no matter which visualization you use

is that it's not taking the shape of the container.

These molecules, I guess you could say these particles,

aren't able to fully slide past each other

but there are still intermolecular forces there

These particles, whether they're molecules or ions,

been able to overcome the intermolecular forces

the way that you might expect a liquid to be,

And this, because it's not taking the shape

and because these molecules or these particles,

It does not have this nice crystalline structure

like we've seen with the crystalline solids.

For example, if you had a little bunch of natural rubber,
