__Question:__ How does the amount of water inside the can affect the volume of the can after being crinkled?
 * __Imploding Can Lab Report__**

__Hypothesis:__ The more the boiling water in the can is, the less likely for the can to be crinkled and have less volume due to the fact that more amount of water takes more time to boil.

__Variables:__ Manipulated Variable- the amount of water boiling inside the can Responding Variable- the crinkliness & the volume of the can

__Materials:__ 4 cans, basketful of water, Bunsen burner, graduated cylinder, stop watch

__Procedures:__ 1) Fill four cans with different amount of water. (10, 20, 30, 40 mL) 2) Boil each of them for 2 minutes. 3) Dump them in the water as soon as 2 minutes’ off. 4) Measure the mass and the amount of water fit inside the can in order to measure the volume of the can.

__Data table:__ Amount of Water ± 2 mL Mass (g) ± 1g Volume (cm³) ± 2 cm³ 10 mL 4.4 97 20 mL 4.6 99 30 mL 3.5 114 40 mL 3.7 172

__Graph:__ I could not access it here,

__Conclusion:__ In this experiment, it was proven that actually the amount of water boiling inside the can affects the volume and crinkliness of the can. As a result, a can with 10 mL got 97 cm³ as a volume and another can with 40mL get 172cm³ as a volume. It tells us that the less water boiling in the same amount of time is, the less volume the can will have. The crinkling process is working because of the fact that the hot water vapors have bigger structure that the water molecules, which means it has bigger pressure when pressing a wall. So as the water boils, more and more vapor molecules produce, they give pressures to the walls and once the hot can is dumped into a bucketful of water, and the expanded can condenses due to the change in molecular structure and the temperature change. However, in this experiment, there were some sources of errors. For example, the degree of dumping can into water (how tilted the can is when dumped), it might have caused some errors in the data. But other than that, the experiment went really well, when I did it again after school.
