Oh, wow, oh, oh, oh, wow, oh, oh, man.

Oh, my life.

And the world. Hello, you're listening to The Science of Everything podcast, episode 27,

Intermolecular B bonds and phase transitions.

I'm your host, James Fodor.

So this episode builds on from what we talked about in episode 15 on chemical bonding.

In that episode, among other things, I talked about intramolecular bonding,

that is the chemical bonds that combine atoms together to form molecules. In this episode, I'll be looking at intermolecular bonds, which are the chemical bonds of a somewhat different

sort, that bind molecules together, or small molecules to form bigger molecules, or that bind

molecules together to form larger substances, like a liquid or a solid, for example.

So some of those include dispersion forces, dipole-dipole bonding, and hydrogen bonding.

And I'll also apply this knowledge of intermolecular forces to explaining how surface tension works.

If you've ever heard of that phenomenon, it's a very interesting one, so we'll take a look at that.

This knowledge of intermolecular bonding will then also be applied to understand phase transitions,

that is, the process by which a substance goes from being a liquid to a gas, or a gas to a liquid,

or a solid to a liquid and so on.

So I'll focus on evaporation, condensation, boiling and melting, and explain

the process by which those occur with reference to knowledge of intermolecular bonding.

Okay, so let's get into it, and I'll start with intermolecular bonding. So, first of all,

we have to know what intermolecular forces are, that is the forces that act between molecules. Intermolecular

forces are forces of attraction or repulsion, which act between neighbouring particles. They

could be ions, ions, atoms or molecules, but generally we're talking about molecules in this
