=Pressure Tester=


 * || Average Pressure (KPA) ||
 * Hot Water || 110.5 ||
 * Control || 99.0 ||
 * Cold Water || 97.9 ||


 * || Degrees (Celcius) ||
 * Cold Water || 5 degrees ||
 * Hot Water || 42.5 degrees ||

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

Our group recorded that the hot water had atoms that move faster so the bottle has more pressure, but the the bottle in the cold water had less pressure because the atoms moved slower. The cold water was 5 degrees Celcius and the hot water was 42.5 degrees Celcius.

What observations did your group make? What did the bottle look like and feel like?

Our group made observations for the Pressure Tester Lab that the hot water made the bottle have more pressure, but the cold water made the bottle have less pressure. The bottle in the hot water was more flexible and squeezable, but the cold water bottle had no room to be squeezed and it was hard.

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

Our group made conclusions that the cold water had atoms that moved slower so the bottle had less pressure although the hot water had much more pressure because the hot water's atoms moved faster.

=Leaky Can=


 * || Temperature (Celcius) ||
 * In Can || 7.4 ||
 * Out of Can || 21.4 ||
 * Humidity || 103.15% ||

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

The temperature in the can was about 7.4 degrees Celcius and the temperature on outside of the can was around 21.4 degrees Celcius. The humidity in the classroom was about 103.15%.

What observations did your group make? What did the metal can look like and feel like both before and after?

Our group said that the outside of the can was sweating and became foggy because the molecules are moving slow. The can started out being just silver and ended up being foggy all over it. We dyed the water blue so we would know that the water just wasn't leaking from the inside of the can.

What conclusions can your group make? Please explain why the metal can did what it did. Please be very descriptive in your explanation.

This lab used the process of condensation because the humidity was above average so the water, instead of leaking, went through the process. The humidity also took part in the condensation because the humidity was above average. The water changed into water vapor because of the high humidity.
