What is Evaporation | Science for Kids?

Evaporation is when liquid turns into gas, just like water from a puddle disappearing on a sunny day.

Imagine you're playing outside and your favorite drink spills all over the ground. At first, it's still liquid, you can see it and maybe even touch it. But after some time in the sun, it starts to vanish, not because someone took it, but because it became gas that you can't see or feel anymore.

Think of evaporation like a party where only certain guests get to leave. The water molecules near the surface are the ones who get excited first and jump into the air as vapor, leaving behind the rest of the liquid. This happens more quickly when it's hot, just like you feel more energetic after playing in the sun.

When you take a bath and the water starts to disappear, that’s evaporation too! It helps dry your clothes, makes clouds in the sky, and even keeps your drinks cool on a warm day, because the liquid turns into gas and takes some heat with it.
