Introduction
This project deals with crushing a can using water pressure as the method of crushing the can. When the can is heated up, the water turns into water vapor and also has a high pressure. When the can is turned upside-down, the steam that was caught in the can will turn back into water due to the different temperatures, cold and hot. The result will be that the atmospheric pressure crushes the can because there is a decrease in pressure inside the can.
Materials:
empty can of soda
cold and hot water
hot plate(anything to heat up water)
thongs
2 bowls
Scientific Principle:
When water boils, it produces steam.The water gas molecules occupy all of the space in the can since the air molecules have been pushed out. The hot gas molecules in the can are at the same pressure as the air on the outside of the can. When the can is put in the cold water upside down, the hot gas water molecules are cooled. Some of the gas molecules are condensed back to the liquid water, so there are less gas molecules present. Cold water also cools the remaining gas molecules, which makes the molecules slow down, which causes fewer collisions with the walls of the can. This causes less pressure inside of the can. The air pressure on the outside of the can is stronger and causes the can to crush.
Procedure:
Start by rinsing out the soda cans to remove any leftover soda goo.
Fill the bowl with cold water (the colder the better).
Pour some water into the empty soda can (just enough to cover the bottom of the can).
Place the can on the burner of the stove while it is in the "OFF" position. turn on the burner to heat the water.
Use the tongs to lift the can off of the burner, turn it upside down, and plunge the mouth of the can down into the bowl of water.
In one swift motion, lift the can off the burner, turn it upside down, and plunge it into the cold water.
