Type in the content of your page here. Using your lab notes, answer the following questions below in the "DISCUSSION" tab located above.

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

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

The bottle in the hot water was really tight. The bottle in the cold icy water was very easy to squeeze.

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

If you put a closed bottle in a tub of hot water, then the bottle will get tight. If you put the bottle in the cold icy water, the bottle gets loose. This is because the bottle is trying to release the energy when it is in the hot water. The hot water puts pressure on the air inside the bottle. The density in the bottle hets high. The pressure is what caused the density inside the bottle. The air is trapped tight. When the bottle is in the cold and icy water, the bottle gets really loose because the pressure in the bottle is low. This makes it less dense in the bottle so the air is not tightly packed. When the pressure is low the density in the bottle is low.
