=**Imploding Can Lab Report**= Research Question: How does the amount of time the can is heated affect its volume when crushed?


 * Hypothesis:** The can will implode more as it is heated longer. Because as the can is heated the air and the water inside the can get more energy and the pressure of the side of the can changes which cause it to implodes more when it was dumped into cold water

-responding variables: the volume of the crushed can (ml) -control variables: 1.The size of the flame, 2. Amount of water in the can, 3. The starting temperature of the water inside the can
 * Variables:** -manipulated variables: how long the can is heated (s)


 * Materials:** empty cans (about ten), tripod stand, Bunsen burner, stop watch, water, bucket, ice, tongs.

2. Heat the can about 10seconds after it starts steaming 3. Turn the can upside down, and dump it quickly into the bucket of ice water 4. Repeat the step above and change the amount of time the can is heated by 10seconds
 * Procedure:** 1. Pour 50ml of water into a can

 * Conclusion:** My hypothesis is wrong, the data don’t have any relationship between each other; which prove that the amount of time the can is heated won’t affect the volume of the can when it was crushed. Because when the can is heated the water inside the can turns into steam and the steam fills the can and replaces almost all of the air inside the can. When the can is dump into the bucket of water ice, the steam condenses into water very quickly, then can is then left with very low pressure inside it which the can got crushed by the strong pressure out side the can. Due to that theory the amount of time it was heated won’t affect the volume of the can after it implodes.
