It is OK to use your textbook, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.


First Name:

Last Name:

School:

 

Data Collection:

1. Select a gas for your experiment by clicking on the appropriate radio button.
Enter the gas you used in your experiment.

Using your mouse, drag the piston to compress the air sample and release the mouse button. Do this at least six times to collect pressure data for volumes ranging from 5mL to 30mL. Record your data in the following table.

2. Enter your data in the table below.

Volume (mL)

Pressure (psi)

3. How would you describe the relationship between pressure and volume as illustrated in the data you collected? (Pick all that apply.)

a) As volume decreases, pressure increases;

b) As volume decreases, pressure decreases;

c) As volume decreases, pressure remains constant;

d) As volume increases, pressure increases;

e) As volume increases, pressure decreases;

f) As volume increases, pressure remains constant;

4. Which of the following graphs best describes the relationship between pressure and volume?

A

B

C

D

E

5. Which of the following best describes the algebraic relationship between P and V in your gas sample? (You may want to do a fast plot of your data.)

a) P/V = constant

b) P + V = constant

c) PV2 = constant

d) PV = constant

e) P = V + constant

6. Watch this video.A small amount of water was added to the container, then the container is heated. When the can is inverted and placed in the liquid water is the pressure outside the container greater than, less than or equal to the pressure inside the container? Explain.

7. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

8. If there is one question you would like to have answered in lecture, what would that question be?
