1)About how much water vapor is in the air? 2) How do animals add water to the air?
3)What happens to the molecules in a liquid when they are heated?
4)What part of a plant gives off water vapor through openings called stomata?
5)What is the gaseous form of water called?

1.At any one instant, the Earth's atmosphere contains 37.5 million-billion gallons of water vapor – enough to cover the entire surface of the planet with 1 inch of rain if condensed.

2.
Animals contribute water mainly through breathing, perspiration and urination. When animals breathe, their warm lungs fill with air. Inside the lungs, some of that air condenses into water vapor.

Hope this helped..
