Evaporation:          

 Evaporation is the process by which a liquid turns into a gas. It happens when the molecules on the surface of a liquid gain enough energy to escape into the air.

Key points:

Evaporation is a natural process that is always happening, even when we can't see it.

The rate of evaporation depends on several factors, including temperature, humidity, wind speed, and the type of liquid.

Evaporation is an important part of the water cycle, which is how water moves between the Earth's surface, atmosphere, and oceans.

Evaporation can also be used to cool things down. For example, sweating helps to cool our bodies down on a hot day.

Real-world examples:

Puddles drying up on a hot day

Wet clothes drying on a clothesline

Water evaporating from a pot on the stove

Remember: Evaporation is a natural process that helps to keep the Earth's water cycle going.
