$300 Question from H1
What instruments are used to measure volume
Temperature and pressure?
$300 Answer from H1
Graduated cylinder, thermometer and a
pressure gauge
$400 Question from H1
What is different about the helium in a balloon
vs. helium in a tank used to fill the balloon?
$400 Answer from H1
The pressure
$500 Question from H1
Why doesn’t a balloon deflate from the air
pressure pushing on its surface?
$500 Answer from H1
There is higher gas pressure inside of the ball
$100 Question from H2
What is the formula for pressure?
$100 Answer from H2
P = F/A
$200 Question from H2
A bicycle pump makes use of what relationship?
$200 Answer from H2
Volume and pressure
$300 Question from H2
Why doesn’t a gas have a definite volume?
$300 Answer from H2
Gas particles are free to move apart or
closer together
$400 Question from H2
As gas particles move closer together what
happens to their volume?
$400 Answer from H2
It decreases
$500 Question from H2
Why should people check the air
pressure in their tires during the winter?
$500 Answer from H2
Air pressure will decrease because of
decreased temperatures
$100 Question from H3
What does constant volume mean?
$100 Answer from H3
The container is closed and rigid.
It does not change
$200 Question from H3
What could cause a helium balloon to burst
as it rises into the atmosphere?
$200 Answer from H3
Decreasing air pressure could allow the balloon
To expand and pop
$300 Question from H3
How does a hot air balloon rise?
$300 Answer from H3
Heating the air causes it to become less dense
than the air outside of the balloon
$400 Question from H3
What factor is unchanged when demonstrating
Charles Law?
$400 Answer from H3
pressure
$500 Question from H3
Force of the atmosphere on a table is 124,500N,
the table has a surface area of 1.5m². What is
the pressure in pascals of the atmosphere on
the table?
$500 Answer from H3
P= F/A = 124,500N/1.5m²= 83,000Pa
$100 Question from H4
As pressure of a gas increases what happens
to its volume?
$100 Answer from H4
It decreases
$200 Question from H4
Name 4 gases.
$200 Answer from H4
Answers will vary
$300 Question from H4
The faster the particles of a gas move
The more frequently they will________ .
$300 Answer from H4
collide
$400 Question from H4
What causes gas pressure?
$400 Answer from H4
Gas particles colliding with the walls of a
container
$500 Question from H4
The graph of Boyles Law shows that its
variables(volume and pressure) have what
kind of relationship?
$500 Answer from H4
Varies inversely
$100 Question from H5
Does the pressure inside of a hot air balloon
Increase when temperature is raised?
$100 Answer from H5
No a hot air balloon has an open bottom so
pressure of the gas inside remains constant
$200 Question from H5
What is a graph?
$200 Answer from H5
A diagram that shows the relationships
between 2 variable
$300 Question from H5
The line graph for Charles Law would pass
through what point?
$300 Answer from H5
The origin(0,0)
$400 Question from H5
Describe the line graphs for both Boyles Law
and Charles Law.
$400 Answer from H5
Boyles Law: curves downward and to the right
Charles Law: A straight line passing through
the origin
$500 Question from H5
Charles Law demonstrates what type of
relationship?
$500 Answer from H5
It is directly proportional
Final Jeopardy
What does directly proportional mean?
Final Jeopardy Answer
It means that 2 variables such as
Temperature and volume will
change in the same way
