The whole can does not need to be submerged just the lip around the open end will do. The can will loudly implode. If one is available use a can that has already has the word Crush on it. Explanation. This demonstrates phase change and the effect of unbalanced pressure. When the water in the can is heated it changes to steam.
When the soda can is plunged into cold water the vapor condenses quickly leaving a vacuum in most of the can. The resulting large discrepancy between the outside and inside air pressure leads to a large net inward force on the can ending with its rapid crushing.
Sep 01 2010 Could someone explain the can crushing experiment As you heat the can to 100 C the water inside starts to boil turning into steam and increasing in volume by a factor of about 600 times. This steam pushes out or displaces most of the air in the can. When you put the can into the cold water the sides of the can cool down rapidly which.
HoW To Crush A Bottle Science Experiment Instructions. Step 1 Gather your materials together and begin by filling your 8 11 pan with ice. Step 2 Carefully pour 12 cup of the hot water into the 2-liter bottle. After the water is in the bottle wait for 2 minutes. As you are waiting make some observations.
Apr 15 2010 One of the popular demonstrations of atmospheric pressure in introductory physics courses is the crushing can or imploding can experiment. 14 In this demonstration which has also been extensively discussed on the Internet a small amount of water is placed in a soda can and heated until it boils and water vapor almost entirely fills the can.
Demo 1 Aluminum Can Crush. Fill the bucket with ice water. Fill the soda can with approximately 1 cm of water. Place the soda can on the hot plate until the water boils.
Jun 16 2011 city Use is worse of all Its 57 Arstnic.. Its a heavy metal does not go away it goes in ground waterlakes streams fish THE BRAND IS SAMAC OR CLOSE TO IT. I worked for city and used it to burn back around the water treatment plant.
Jan 18 2016 OK you can do this at home---but remember the can is hot. Just use common sense. If you dont have an electric stove burner you can put the can with water in a pot of boiling water.

May 04 2012 Re Can someone explain the law behind the can crushing experiment Probably the best approach to an explanation of this demonstration is in terms of equilibrium vapour pressure. If you have liquid water there is always a little bit of gas phase water water vapour in equilibrium with it. At the freezing point the amount of water vapour.

Collapsing Metal Can Boyles Law Description A metal can is crushed when immersed in cold water. Materials Empty soda can Beaker Ice water Bunsen burner Procedure Add 15 mL of water to aluminum can and bring to a vigorous boil. Quickly invert the can and submerge it into the beaker filled with ice. At this point the can will collapse.
The Explanation The air pressure inside the can is equal to the air pressure outside it. The thin metal of the can has equal forces pressing on it from either side and experiences no overall force.. When you boil the water in the can the water evaporates to form steam.
Can Crusher Experiment. Share this activity. This can crusher experiment is the perfect way to demonstrate the wonders of pressure and condensation. All you need is the power of air and water to produce the amazing end result a crushed soda can Download free activity. Subject.
May 06 2021 You can crush a soda can using nothing more than a heat source and a bowl of water. This is a great visual demonstration of some simple scientific principles including air pressure and the concept of a vacuum. The experiment can be performed by teachers as a demonstration or by mature students under supervision.
