Q1. What data did your group record? Include temperature and pressure values using correct SI units The data is on the computer in you room.

Q2. What observations did your group make? What did the bottle look like and feel like? A2. The bottle felt like a regular bottle of plastic. It was a two liter empty bottle. When it went from the hot water to the cold water the bottle crushed in on itself, when the bottle went from cold to hot water it inflated. Part of the reason it expanded is becasue there is more pressure in hot water and more pressure is added into the bottle.

Q3. What conclusions can your group make? Please explain why the bottle did what it did in the two different baths.

A3. When the bottle was put in the hot the bottles pressure expanded becasue hot air and water expand. Then when placing it quickly into the ice cold water the bottles was sucked in on itself, because the pressure was too great and cold air compresses which made it crush in on itself.

1. DATA ON COMPUTER 2. The metal can had a lot of condensation on it but it was clear not green even thought the water inside of the can was green. Before the outside of the can was all smooth then after the can was all wet because it had condensation around the can 3. The condensation on the can was not from the water inside of it, it was from the steam on the side the particles form the steam are moving very quickly because there is more energy in it, but when it meets the cold can, it forms water droplets because of the change in temperatures. **
