[Beginning]
Little Complication you’re the razor pressed against my skin
Little Complication you’re the sweetest sight of sin

[Verse 1]
Kill off this common sense of self-definition
Take away these fears of losing what’s important
Nothing’s how it should be, and everything’s how it isn’t

*You’re the complication digging in my brain
Delivering me the best kind of pain
When I am left with nothing at all
I always seek your comforting call

[Verse 2]
Make me taste this lack of admiration for all my hopes
Set flame to my insides and burn all these colors
Your trust is useless, and uselessness is trustworthy

[Verse 3]
Complication, Complication, where do you leave us when the music stops?
My little complication, you’ve got your heart slipped in the slots
Gamble what you’ve left, and keep nothing kind
Tear my heart like paper, I promise I don’t mind

Boyle’s Law: Pressure-Volume Relationship in Gases

Purpose:
To determine the relationship between the pressure and volume of a confined gas.
Materials:
•Computer
•Vernier Computer Interface
•LoggerPro
•Vernier Gas Pressure Sensor
•20 mL gas syringe

Procedure:
1. Prepare the computer for data collection by opening the file “06 Boyle’s Law” from the Chemistry With Computers folder of LoggerPro.
2. To get the best data, you will need to correct the volume readings from the syringe. Look at the syringe; its scale reports its own internal volume. However, that volume is not the total volume of trapped air in your system since there is a little bit of space inside the pressure center.

To account for the extra volume in the system, you will need to add 0.8mL to your syringe readings.
3. Click Collect to begin data collection.
4. Collect the pressure vs. volume data.
a. Move the piston to position the front edge of the inside black ring at the 5.0 mL line on the syringe. Hold firmly in this position until the pressure value stabalizes.
b. When the pressure reading has stabalized, click “Keep”. Type the total gas volume in the edit box. Remember- you are adding 0.8 mL to the volume in the syringe for the total volume. Press the “Enter” key to keep this data pair.
c. Move the piston to the 7.0 mL line. When the pressure reading has stabalized, click “Keep” and type the total volume, 7.8 mL.
d. Continue this procedure for syringe volumes of 9.0, 11.0, 13.0, 15.0, 17.0, and 19.0
e. Click “Stop” when you have finished.
5. In your data table, record the pressure and volume data pairs displayed in the table.
6. Examine the graph of pressure vs. volume. Based on this graph, decide what kind of mathematical relationship you think exists between these two variables, direct or inverse. To see if you have made the right choice:
a. Click the “Curve Fit” button.
b. Choose Variable Power (y=Ax^n) from the list at the lower left. Enter the power value, n, in the Power edit box that represents the relationship shown in the graph. Click “Try Fit”.
c. A best-fit curve will be displayed on the graph. If you made the correct choice, the curve should match up well with the points. If the curve does not match up well, try a different exponent and click “Try Fit” again. When the curve has a good fit with the data points, then click “Okay”.
7. With the best-fit curve still displayed, proceed directly to the Processing the Data section.

Processing the Data:

1. When you double the volume, you cut the pressure in half. If the volume was 5 with a pressure level of 180, then a volume of 10, would have a pressure of 90.
2. If 20.0 mL of volume has a pressure of 45 kPa, then 10 mL has 90 kPa of pressure.
3. The pressure went down by about 3 times when the volume was tripled.
4. The relationship between pressure and volume is inverse because when the volume goes up, the pressure goes down.
5. The pressure would decrease if the volume was increased to 40.0 mL because they are inversely related.
6. If the volume was decreased to 2.5 mL, the pressure would increase, as shown in the data.
7. The constants in this expirement where the syringe and the amount of air that was used, because neither of these things changed.
8. See data
9. See data
10. K=P•V
Conclusion:
1. When using a syringe to measure the pressure of air, the data showed that there’s some relations between the pressure of air and the volume of the area it’s in.
2. One of the relation is the changing of pressure and volume; when volume goes up, pressure goes down, and vice versa.
3. For example, the volume is 5 mL and the pressure is at 180 kPa, if the volume is multiplied by two and get 10 mL, the pressure is cut in half to 90 kPa.
4. This shows that if the volume is low, the pressure will be high, and if the volume is high, the pressure will be low.
