Q: What data did your groupd record? A: Hot Bath- 109.14 Cold Bath- 97.82 No Bath- 98.73
 * __Pressure Tester__**
 * Pressure (kPa):**

Hot Bath- 40.6 Cold Bath- 3.7 No Bath- 20
 * Temperature (degrees Celsius)**

A: When the bottle was placed in the cold water, the bottle felt thin and empty. The bottle felt empty because in the cold water, the atoms in the bottle were moving slower. In the hot water, the bottle expanded and felt more full and firm. The bottle felt more full because the atoms were bouncing off each other faster.
 * Q: What observations did your group make? What did the bottle look like and feel like?**

A: In the hot bath, the bottle felt full and expanded because the atoms in the bottle were bouncing off of each other. Because they were bouncing off each other at such a rapid pace, the bottle expanded and felt firm. In the cold bath, the bottle condensed and felt thin because the atoms were moving slower. Since the atoms were moving slower, the atoms didn't bounce off each other as quickly, making the bottle feel empty. But, the same amount of air was in the bottle when we put the bottle in the baths. The above happened because atoms bounce off of eachother faster in the hot water than the cold water. This experiment explains Charles's law. Charles's law states that at a constant pressure, the temperature affects volume. This also occured in both tubs.
 * Q: What conclusions can your group make? Please explain why the bottle did what it did in the two different baths.**

__**The Leaky Can**__ A: Temperature of empty can: 21.2 degrees celcius Temperature iwth ice: 5.2 degrees celcius Relative Humidity: 77.22 %
 * Q: What data did your group record?**

A: At first, the can was shiny and luke warm. However, once the ice water and blue dye was put in the can, the outside of the can was covered with condensed water ( the amount of the condensed water on the can kept growing as time passed), and the can was cold. The condensation on the outside was clear, not blue.

**Q: What conclusions can your group make?** A: At first, the can was lukewarm and no water had condensed on the outside of the can. However, when the can was filled with the ice water that was colored blue, some of the gas around the can condensed onto the can. This is because the temperature of the can's surface was below water's boiling point, so the gas in the air condensed onto the can. Because the mist around the can wasn't blue, the mist had to be gas from around the can. The steam from the boiling water added humidity to the air around the can. This proved that the can wasn't porous. The water from the steam was on the outside of the can because of the cool temperature of the can.
