Place a soda bottle in the sink and let hot water run into it up to the top. Shut off the water when the bottle is full. Watch the surface of the water carefully. You will soon see the level of the water drop. After ten minutes it will be down about a half inch or more. The water has shrunk. . Can you make the water return to its original size? Put the bottle of water into a large pot that contains some water. Heat the pot gently, on the stove. The water inside the soda bottle soon begins to rise. It may even reach the top and spill over. With very few exceptions, materials expand (become larger) when heated, and contract (become smaller) when cooled. So, when the hot water in your soda bottle cooled off, it took up less room. But when you heated it in the pot, the water expanded and returned to its original level. ORIGINAL LEVEL LOWEST LEVEL ^. y. J /y .
