Here's a breakdown of what happens:
* Heat Energy: When liquid water absorbs enough heat energy (usually from the sun or another heat source), the water molecules start to move faster.
* Breaking Bonds: This increased movement causes the weak bonds holding the water molecules together to break.
* Escape: The individual water molecules now have enough energy to escape the liquid's surface and become water vapor, which is the gaseous state of water.
Note: Evaporation can also occur at temperatures below water's boiling point (100 degrees Celsius or 212 degrees Fahrenheit). This is why puddles dry up even when the air isn't boiling hot.
