$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?

$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
