Hi there, we want to know why intermolecular forces are important.
00:07
So i'm just going to abbreviate them as ion forces.
00:11
So intermolecular forces, as the name implies, are forces of attraction between molecules.
00:26
So we're talking about molecular compounds here.
00:33
So we know that ion charges hold ionic compounds together, and covalent bonds hold atoms together to form molecules.
00:42
But when we have molecules, we need intermolecular forces to hold the molecules together.
00:50
So these are going to hold molecules together.
00:54
You might ask, well, why is that important? well, let's think about the states of matter.
01:02
We know that in a gas, the particles are spread out, not touching, moving rapidly, filling their container.
01:11
When we have a liquid, however, the particles are touching.
01:17
They're held together fairly strongly, but not so strongly that they can't slide past one another, which is why a liquid flows...
