It evaporates into the air. Show the animation Evaporation. Explain that water molecules leave the liquid state and form water vapor, a gas. The molecules in water vapor become part of the air. The ...

Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid ...

This causes the water vapor molecules to slow down. When they slow down enough, their attractions overcome their speed and they stay together as liquid water. Note: The particles on the side of the ...

For the first time, researchers have collected detailed measurements of water vapor high above the surface of the Greenland ...

water can exist as a liquid and a gas at the same time, for example, in cloud formation: Depending on the temperature, water vapor in the air condenses into liquid droplets. The theory of phase ...

FARGO — Humidity is water vapor, which is a clear gas ... When water falls from a cloud, it is precipitation. Liquid precipitation is rain or freezing rain. If the drops are smaller than ...
