Which Molecules Escape When Water Evaporates?

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

What is released when water evaporates?

Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

Why molecules can escape during evaporation?

Evaporation turns liquids into gas. Evaporation can take place at temperatures below boiling point since the molecules in the liquid have different energies. As the molecules in a liquid collide, some achieve higher energies, allowing them to escape.
