Here's why:
* States of Matter: Water can exist in three states: solid (ice), liquid (water), and gas (water vapor).
* Water Vapor: Water vapor is the gaseous form of water. It's invisible and forms when liquid water evaporates, meaning it changes from a liquid to a gas.
* The Process: When water molecules absorb enough energy (like heat from the sun), they move faster and break free from the liquid, becoming water vapor.
So, water vapor doesn't *turn into* a gas; it *is* a gas.
Perhaps you were thinking of a different process, like:
* Evaporation: This is the process of liquid water turning into water vapor.
* Condensation: This is the process of water vapor turning back into liquid water (like when clouds form).
