Collapsing can experiment, 1 of 3. A small amount of water is added to a thin-walled metal can which is then placed on a hot plate until water is boiling (Photo 1). As liquid water boils, it produces water vapor that displaces air from the can. The hot plate is then turned off and the can is closed. As it cools down, water vapor inside the can condenses to liquid that takes significantly less volume than vapor. Therefore pressure inside the can drops considerably below the outside atmospheric pressure. The pressure difference then forces the can to collapse (Photos 2 and 3). | |
