Evaporation
When a liquid slowly turns into a gas (even below boiling point), that's evaporation. It's why puddles dry up.
Condensation
When water vapour cools down and turns back into liquid drops — that's condensation. It's why cold drinks 'sweat'.
The water cycle
Evaporation from oceans → clouds → rain → rivers → back to the sea. Water never goes away!

Did you know?
The water you drink today might be the same water a dinosaur drank millions of years ago — water just keeps recycling!
Try it at home: Make a mini cloud
- Pour hot (not boiling) water into a glass jar.
- Place a plate of ice cubes on top.
- Watch — a small cloud forms inside! You just saw evaporation and condensation.
