Mrs. Smith put 3 cups of water in a pot on the stove and turned it on to "high." She let the water boil for a few minutes, and then took it off of the stove to cool. Once the water had cooled, she measured it again, and found that there was only 2 3/4 cups left. What happened to the water?
Mrs. Smith spilled the water on the floor.
The water vaporized into steam and left the pot.
The water transformed into carbon dioxide gas and floated away.
The water froze onto the bottom of the pan.
