Use the words evaporate, water vapor, warmth, wind and surface area.
Read the passage. Then circle the best answer.
When liquid water turns into a gas, we call it evaporation. The gas is called water vapor. It is invisible and mixes into the air.
Evaporation happens all the time, even when water is not boiling. That is why puddles dry up and wet clothes dry when they are hung up.
Three things make water evaporate faster: warmth (heat from the Sun or a heater), wind (moving air carries the water vapor away) and a bigger surface area (spreading the water out so more of it touches the air).
Water evaporates more slowly when it is cool, the air is still, or the water is deep and in a narrow container.
Write True or False.
