A.Place water in a pot, heat it, and observe it boil away into water vapor.
B.Place a tray of water into the freezer and observe it turn to ice.
C.Place a glass of ice outside and observe it melt into water.
D.Place a cold glass of water on the counter and observe it for changes.
C. Place a glass of ice outside and observe it melt into water.
