 * PRESSURE TESTER:**
 * Evaporation- Change of the state of a liquid into a gas.
 * Condensation- Change from a gas into a liquid.
 * Freezing- Change from a liquid to a solid.
 * Metling- Change from a solid into a liquid.
 * Sublimation- Change from a solid straight into a gas.
 * Boiling- change from a liquid into vapor.

//__What observations did your group make? What did the bottle look like and feel like?__// Because the particles in the cold water were packed much tighter, it created more pressure on the bottle. This made the bottle shrink a little. When the bottle was put in the hot water, the particles in the bottle had enough room to expand. When in the hot water, the bottle was smooth and unharmed. When in the cold water, you could actually see the bottle shrinking.

// __What conclusions can your group make? Please explain why the bottle did what it did in the two different baths.__ // When the bottle was in the hot water, it had more pressure than when it was in the cold water. This is because the molecules are moving faster and spreading apart. So when placed in the hot water, the bottle expanded. The bottle shriveled up in the cold water because the molecules are slowing down and moving closer to each other. . The cold water didn't resist as much. Description of bottles during experiment- Cold- Squishy and shriveled when in the cold water Hot- Hard and hard to push down. Not shriveled.

THE LEAKY CAN:
//__What data did your group record? Include temperature and pressure values using correct SI units__// The Temperature and pressure values are also on Logger Pro.
 * Data- We cannot get to the data for this experiment at this time. We will upload it as soon as possible. - can whoever measured the data post it from their school account? ~ASM **

__//What observations did your group make? What did the bottle look like and feel like?//__ The can (before it collected condensation because of the steam coming out of the boiling pot of water) was cold and dry. The hot steam that was created from the pot stuck onto the cold surface. That is why the outside didn't turn blue like the inside of the can.

//__What conclusions can your group make?__// The hot steam mixed with the air and stuck to the cold surface of the can. This process is called condensation. Condensation is the conversion of a gas into a liquid. The blue water on the inside of the can had nothing to do with the condensation, except for the fact that it's temperature attracted the steam. This is proved from the water on the outside. It did not appear blue, so it was obviously not the water from the inside.
