Aluminum Can Lab
Pose a Question
How does the initial amount of water in a can affect the resulting amount amount of water in the can after it has been heated to boiling point and submerged into a bowl of water?
We hypothesized that the higher amount of water in the can initially, the more water will result in the can. We created this hypothesis for a few reasons. The first reason was that, we thought that little to no water would leave the can when it was submerged in the room-temperature water. We also though that since the can imploded, it would create a vacuum effect and bring water in.
Collect and Interpret Data
Hot Plate
Stop Watch
Aluminum can(12oz)
Beaker Tongs
Plastic Water Basin
Cool Water
1. Fill the can with the decided amount of water and record it
2. Put the can on the hot plate and wait until the water reaches 100 degrees Celsius
3. Use the beaker tongs to flip the can into the bin of water, make sure the opening of the can in submerged
4. Wait for the can to "pop" from the implosion
5. Pour the remaining water from the can into a graduated cylinder and measure the amount of water
6. Repeat steps 1-5 as many times as needed for your trials
The Aluminum can lab sought an answer to the question, "How does the initial amount of water in a can affect the resulting amount amount of water in the can after it has been heated to boiling point and submerged into a bowl of water?" The experiment didn't support our hypothesis because on trial 2 we had 30 ml of water that resulted in 31 ml of water and on trial 3 we had 40 ml of water which resulted in 23 ml of water.
One of the errors that could have affected our results of the experiment could include, not removing the can of water from the bucket fast enough or
another error that could have affected the results of the experiment could have been dunking the can before it reached 100.00ºC. Another investigation that could further support our hypothesis could be repeating the experiment and being more careful of the errors described above.
Conclusion Continued
1. As the can was heating up the molecules began to move faster, the molecules also began to bump into each other as the molecules accelerated.

2.While the molecules were speeding up the liquid/water in the can was changing into a gas form. The air pressure in the can went up due to the molecules increased energy which led to faster moving molecules that made the can have a higher air pressure.

3.The pressure of a liquid or gas try to be even as possible so therefore the high pressure gas has more energy to flow to the low pressure air.
4.When we dunked the can into the cold water the steam became a liquid due to the lower temperature of the liquid/water in the bucket which cooled the steam.

5.Due to the implosion the can had less volume when it was dunked into the cool water.

6.The pressure of the water is higher than that of the can so that is what caused it implode
