Charles and GayLussac'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 GayLussac'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?
