A pure substance has one type of particle. Think gold bars, pure salt, or distilled water. No extras. No friends. Just H₂O molecules hanging out alone.
Now, tap water is the opposite—it’s a mixture. It has chlorine, fluoride, calcium, and even tiny bits of fish pee. Yup, you drank fish pee. Distilled water? None of that. It’s the lonely hermit of the water world.
To make distilled water, you boil regular water. The steam escapes, leaving all the minerals and impurities behind. Then you cool the steam back into liquid. It’s like a water rebirth—pure and drama-free.
The Quirky Science Behind It
Here’s where it gets geeky: pure substances have fixed melting and boiling points. Distilled water boils at exactly 100°C (at sea level). No messing around. But a mixture? It boils over a range of temperatures. Science’s way of saying, “You’re not special.”
Fun fact: distilled water is not a good conductor of electricity. Because there are no dissolved ions (like salt), it’s an insulator. You could drop a toaster in it and be fine—do not try this at home. Actually, don’t try it anywhere.
But wait—there’s a twist. When you leave distilled water in an open glass, it starts absorbing stuff from the air. Dust, microbes, and CO₂. Within hours, it becomes a mixture again. Pure water is a diva—it can’t stay pure forever.
