 * Pressure Tester**

What data did your group record? Include temperature and pressure values using correct SI units Hot Water = 47.6 c pressure= 102.47 kPa

Cold water= 4.7 c pressure = 97.82 kPA

What observations did your group make? What did the bottle look like and feel like? The Bottle felt tight and like their was lots of air in the bottle when you would squeeze it. This happened for both bottles...but more for the hot water.

What conclusions can your group make? Please explain why the bottle did what it did in the two different baths?

A conclusion of this experiment can be that when recording the pressure in cold and hot water that there is a difference in pressure but not a big difference. Both Bottles got air tight and this is because the bottle was being held down in pressure.


 * Leaky Can**

What data did your group record? Include temperature and pressure values using correct SI units

without anything: temperature outside: 22.6 c temperature inside: 23.6 c humidity: 59.36%

After: temperature inside: 2.5 c temperature outside: 21.6 c humidity: 68.96%

What observations did your group make? What did the bottle look like and feel like? Before: metal can has a black/gray inside and the outside silver, aluminum/ metal

After: outside water clear/ white, can foggy inside water blue cause used blue food dye... condensation from humidity, air

What conclusions can your group make? Please explain why the bottle did what it did in the two different baths.

A conclusion for this experiment is that the bottle fogged up because the outside of the air was warm but the inside of the can was cold. its just like being in the car in the winter when the car is hot but the outside is cold so the windows fog up. Another thing to add the reason the food dye did not change the color of the vapor was only the water condensates not anything added.
