Beginner's
Guide to Propulsion
Charles and Gay-Lussac's
Law
Activity
If so instructed
by your teacher, print out a worksheet page for these problems.
Before you begin:
Open
The
Beginners Guide to Propulsion and click on the
Propulsion
Index. Under Statics Gases, open the slide titled
Charles
and Gay-Lussac's Law. Read the information and use it to complete
the activity.
Answer the questions
shown below:
- Explain what
the phrase "volume is directly proportional to the temperature" means
to you.
- If T = 1000 K
and V = 10 cu. m., what does C equal?
- Using that value
for C, find:
a. V, when T = 1,100 K
b. V, when T = 1200 K
c. V, when T = 800 K
d. V, when T = 1,400 K
- Plot these points
on a graph, or use the plot feature on a graphic calculator. Describe
the graph.
- Open the animated
version of Charles and Gay Lussac's Law slide. How does your graph
compare to the graph shown here?
- Use your graph
to find:
a. V when T = 2,000 K
b. V when T = 600 K
c. T when V = 15 cu. m.
d. T when V = 3 cu. m.
- Now check your
answers for problems 3 and 6 by using the ratio V/T = C. Were they
the same? Why or why not?
- Take a look at
your answer to question 1, does your graph agree with that answer?
Why or why not?
