Every compound is like a tiny, dramatic friend at a party. The molecules are constantly bouncing around, and the boiling point is the exact moment they get so fed up with being liquid that they scream, “I’m out!” and turn into gas. That’s literally it. The stronger the “friendship” (or intermolecular forces) between the molecules, the hotter you have to make them to break it up. Think of it as the emotional temperature of the crowd.
If the molecules are holding hands tightly (like in water), you need a lot of heat. If they’re just awkwardly waving at each other (like in lighter fluid), they’ll bail at a much lower temp. It’s all about molecular drama and how clingy the little guys are.
